After having defended his doctoral thesis in high voltage engineering in 1987 he started working at ABB in Västerås. During his 13 years at the company he had several positions and worked as head of research, developing technology for measurements of diagnostics and monitoring of insulation systems and electrical power devices. In addition, he has invented and developed products in power generation. Most known is perhaps the Powerformer, a high voltage generator for connection to the grid without any intermediate transformer.<br /><br /><strong>Developing renewables</strong><br />Since 2000, Mats Leijon is a Professor in electrical science at Uppsala University. He has got about 1500 patents and has published more than 300 scientific articles. Developing renewable energy sources by using waves, wind and tidal currents have become his specialty. In parallel he has started the company Seabased, which plans, builds and installs complete, grid-connected wave parks at sea. Research and demonstration facilities are located outside Lysekil.<br /><br />He is now phasing out part of his many commitments to be able to take on the assignment at Chalmers.<br /><br />&quot;I look forward to combining theory and practice to a larger extent than I have been able to do previously in academia&quot;, says Mats Leijon. “Here at the division of Electrical Power Engineering, there are good laboratory activities.”<br /><br />In his opinion, setting high goals is crucial to success.<br /><br />“First of all, I'm going to familiarise myself with the research activities here, and then apply for funding to do exciting research, but it is still too early to say in what areas this will be.”<br /><br /><strong><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/E2/Profilbilder%20Elkraftteknik/Mats-Leijon_300x300px.jpg" alt="" style="margin:5px;width:250px;height:250px" />Important to do one´s homework</strong><br />“As a researcher, it is important not to limit your mind. One prerequisite is that you have done your homework and have a solid and stable knowledge base founded in basic theory”, Mats emphasises. “That gives you qualifications to take responsibility for development in society.”<br /><br />&quot;In order to implement your ideas, as an engineer, you can´t ignore what is possible to put into practice and what is commercially viable”, he states. “It is important to understand how your own research fits into the big picture.”<br /><br />He sees the conformity within academia as a problem.<br /><br />”People of the same type tend to choose the same type of solutions. The question is then if the right solutions really are highlighted? At Uppsala University, women account for about 40 percent in the field of electrical engineering. Perhaps I have some lessons learnt, that I could bring here”, Mats Leijon concludes.<br /><br />Text: Yvonne Jonsson<br /><br /><strong>Contact: </strong><a href="/en/Staff/Pages/Mats-Leijon.aspx">Mats Leijon</a>, Professor, Department of Electrical Engineering, Chalmers Fri, 16 Feb 2018 08:30:00 +0100https://www.chalmers.se/en/departments/e2/news/Pages/International-award-in-mechanical-pulping-to-Anders-Karlstrom.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/International-award-in-mechanical-pulping-to-Anders-Karlstrom.aspxRewarded for new paradigm in pulping technology<p><b>​The Arne Asplund Mechanical Pulping Award 2018 has been granted to Professor Anders Karlström, Head of the department Electrical Engineering at Chalmers.</b></p>​The award is given out every two years by Arne Asplund Mechanical Pulping Award Foundation to promote the development of new technology for the manufacture of high-yield pulp. It is awarded in recognition of outstanding achievement in research and development of mechanical pulping technology.<br /><br /><span>“To receive this award is a great honor for me”, Anders Karlström says. “I have been working with this for many years and it feels fantastic to get a confirmation that the struggle really has been worthwhile.”<span style="display:inline-block"></span></span><br /><br />The justification for the award reads as follows: “Based on his deep understanding of the fundamentals of refining in mechanical and chemimechanical pulping, Anders Karlström has initiated a paradigm shift regarding the theory of refining by introducing the entropy model. This new approach offers tools to understand the interplay in the refining zone with regards to refiner operation, plate patterns and the produced pulp quality. These new findings are already in use in several production lines offering a set of possible ways to optimise quality and specific energy input.”<br /><br />The award consists of a gold medal and an honorarium of SEK 25,000. The prize ceremony will take place at the International Mechanical Pulping Conference, IMPC, in Trondheim on 29 May. <br /><br />Regarded as the &quot;Nobel Prize&quot; in the field of mechanical pulping, the Arne Asplund Mechanical Pulping Award was established in 1985 to commemorate the Swedish engineer Arne Asplund’s contribution to the pulp and paper industry worldwide. He was the inventor of the thermomechanical pulping technique, known as the defibrator-method, also called the Asplund-method, for pulping wooden chips.<br /><br /><a href="http://www.valmet.com/media/news/press-releases/2018/the-arne-asplund-mechanical-pulping-award-2018-granted-to-anders-karlstrom/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release</a><br /><br /><strong>Contact:</strong> <a href="/en/Staff/Pages/anders-karlstrom.aspx">Anders Karlström</a>, Professor and Head of the Department Electrical Engineering, Chalmers<br />Thu, 15 Feb 2018 13:00:00 +0100https://www.chalmers.se/en/departments/physics/news/Pages/Patrik-Johansson-in-charge-of-European-battery-research-network-.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Patrik-Johansson-in-charge-of-European-battery-research-network-.aspxIn charge of the largest battery research network in Europe<p><b>​​Patrik Johansson, Professor at the Department of Physics at Chalmers, has been elected new co-director of a large European battery research network – Alistore European Research Institute (Alistore-ERI).</b></p><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Patrik_Johansson200x270.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />The network is the largest academic-industrial collaboration on batteries in Europe and aims to tackle battery challenges and move towards sustainable energy solutions. The network has about 25 partners, with academic entities such as Cambridge, Oxford and Collège de France, and Bosch, Saft,  BASF and Renault on the industry side.<p></p> “Due to the current electromobility (r)evolution and the need to efficiently store renewable energy, Alistore-ERI is more important than ever before. As researchers, we create projects and share ideas within the network and get important feedback from other academics and the industrial partners,” says Patrik Johansson, who takes part in several national and international projects to develop the next generation of batteries.<p></p> Patrik Johansson will mainly be responsible for strategies for expansion of the network, to increase the internal and external interactions, as well as taking part in defining the research strategy. <p></p> “My role will be to build an even stronger network for future challenges – an inspiring task with many openings for Swedish industry as well,” says Patrik Johansson. <p></p> He will officially start his new assignment on 1st of January and will share the direction with Prof. Christian Masquelier from France and Dr. Robert Dominko from Slovenia. <p></p> Text: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a><br /><br /><a href="http://www.alistore.eu/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more about Alistore-European Research Institute (Alistore-ERI).</a><br /><a href="/en/Staff/Pages/Patrik-Johansson0603-6580.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about Patrik Johansson and his research at Chalmers University of Technology.</a><br />Thu, 14 Dec 2017 00:00:00 +0100https://www.chalmers.se/en/news/Pages/Top-scientists-in-sustainable-energy-gathers-at-Chalmers.aspxhttps://www.chalmers.se/en/news/Pages/Top-scientists-in-sustainable-energy-gathers-at-Chalmers.aspxTop scientists in sustainable energy gathers at Chalmers<p><b>​On 6-8 December, the Sustainable Energy Symposium is held at Chalmers, in collaboration with the Molecular Frontiers. The seminar brings together world-leading researchers from several science disciplines to present the latest advances within the field.</b></p>​ <br />The conference gathers distinguished researchers, industry representatives, decision makers and an engaged public for presentations and discussions on future energy solutions. Development of sustainable technologies for solar energy, batteries and energy storage is needed to make the necessary switch from fossil fuels to renewable energy sources. During the conference, the latest advances in the field will be highlighted, and the content will be made available to the public. Through live broadcast at <a href="http://www.youtube.com/molecluestv" target="_blank">Molecular Frontiers YouTube Channel</a>  you will be able to follow the conference even if you are not in place. <br /><br /><br /><strong>150 high school students participate</strong><br />Sustainable Energy Symposium is a unique event in several ways – about half of the conference participants are high school students. This is possible thanks to the Molecular Frontiers Foundation which offers a scholarship for students from all over the country to come. The Molecular Frontiers emphasize in particular the importance of being curious and asking good questions. Approximately 150 students from all over the country are given the opportunity to listen to and ask questions to world-leading researchers.<br /><br /><br />Among the speakers are noted:<br /><br /><strong>Steven Chu, Nobel Prize winner in Physics 1997 and Obama's Energy Ministers 2009-2013.</strong><br />Steven Chu was awarded the Nobel Prize in Physics in 1997 for his work on laser cooling of atoms. Since then, his research has increasingly been about solving the challenges of climate change and sustainable energy supply. In 2009, Barack Obama appointed him the United States Secretary of Energy, and became the first scientist in an American government. After his time as Energy Secretary, he returned to research but remains a prominent debater focusing on renewable energy and nuclear power. He emphasizes the importance of reducing fossil fuel use to address global warming and climate change. He has put forward a number of innovative and sometimes controversial proposals for action.<br /><br /><strong>Paul Alivisatos, University of California at Berkeley</strong><br />Paul Alivisatos is a pioneer in nanotechnology, focusing on inorganic nanocrystals. By controlling the size and surface of the nanocrystals, his research team can tailor their properties and produce materials for a variety of applications, including solar cells and materials to reduce carbon dioxide into hydrocarbons. He has developed quantum dots, small semiconductors that are isolated from the environment and are extremely effective in absorbing and transmitting light. These are already used in the most energy efficient and high quality television screens in market today.<br /><br /><strong>Daniel Nocera, Harvard University</strong><br />Two inventions of Daniel Nocera may be of great importance in the future. The artificial leaf, mentioned in Time magazine’s list of Inventions of the Year 2011, mimics the photosynthesis, and splits water into hydrogen and oxygen by using sunlight. A further development of the concept is the bionic leaf, which takes carbon dioxide from the air and combines it with hydrogen from the artificial leaf to produce biomass and liquid fuel. In this way, a cycle is achieved that is much more efficient than photosynthesis in nature, which can contribute to a green and cheap production of fuel and food.<br /><br /><br /><strong>Program</strong><br /><a href="/en/conference/sustainableenergy/Documents/Program_Sustainable_Energy.pdf" target="_blank">Here you will find the entire program for the conference &gt;</a><br /><br /><br />Plenary lectures 7-8 December:<br />• <strong>Steven Chu</strong> – <em>Climate Change and innovative paths to a sustainable future</em><br />Nobel laureate in Physics 1997, former United States Secretary of Energy.

Selma Brynolf is the new coordinator for the profile Sustainable Vehicle Technologies in Chalmers Areas of Advance Transport and Energy.</b></p>​“It's an exciting assignment and I look forward to learning more about the research on transport and sustainable vehicles that is conducted at Chalmers and University of Gothenburg.”<br /><br />As post-doc at the department of Space, Earth and Environment at Chalmers, Selma Brynolf has evaluated the environmental impact of marine fuels from a lifecycle perspective and worked with modeling of energy systems. Since October 2017, she will also coordinate Sustainable Vehicle Technologies, a profile shared between the Areas of Advance Transport and Energy. She will work together with Anders Nordelöf, who continues his assignment as vice coordinator.<br /><br />“I currently work with two main questions”, says Selma Brynolf. “Evaluation of possible future fuels and propulsion technologies for shipping, as well as the role that fuels produced from carbon dioxide and water using electricity could have in the transport sector.<br /><br />Maria Grahn, previous coordinator of Sustainable Vehicle Technologies, is now director of Chalmers Energy Area of Advance.<br /><br />“I am pleased and proud to announce a new, strong leadership for Sustainable Vehicle Technologies. Handing over to Selma Brynolf and Anders Nordelöf feels very good, I am certain that the work will be continued in the best possible way.”<br /><br />Selma points out that an important and challenging part of her research is to find sustainable solutions for all modes of transport. She believes that electrification is a possibility for many parts of the transport sector, not just for cars, and that it is very exciting to follow the development.<br /><br />“But there are many more areas that need to be developed. I also believe that we need to think again and change our view of transport in general and the benefit they give us. I hope to contribute to a slightly more sustainable transport sector.”<br /><br />Text: Julia Jansson och Emilia Lundgren<br />Fri, 03 Nov 2017 10:05:00 +0100https://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/New-research-opportunities-as-ElectriCity-grows.aspxhttps://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/New-research-opportunities-as-ElectriCity-grows.aspxNew research opportunities for Chalmers researchers as ElectriCity grows<p><b>​ElectriCity, best known for the electric bus 55 in Gothenburg, is much more than just the bus. As the project grows, new exciting opportunities for research appear. Per Lövsund, coordinator for ElectriCity at Chalmers University of Technology, invites Chalmers researchers to contact him with ideas.</b></p><p><br /></p> <p>“We can perform research projects, master and bachelor thesis projects within ElectriCity, and thereby gain better dissemination and utilisation of our results”, says Per Lövsund, who calls on Chalmers researchers to contact him with ideas for new projects.<br /></p> <p><br /></p> <p>ElectriCity is now growing to include for example smaller trucks, such as waste trucks and distribution cars. This means exciting opportunities for several research areas, Per Lövsund explains. Self-driving vehicles, safety, community planning, noise, thermal optimization, control algorithms, vehicle dynamics, development and recycling of batteries and fuel cells, and charging station requirements are some examples of questions from different research fields, all of which can be studied within the framework of ElectriCity.<br /></p> <p><br /></p> <p>Researchers involved in ElectriCity have access to research platforms such as buses and other vehicles. The project’s demo arena also includes the new urban area Frihamnen and the development of south Chalmers Johanneberg Campus, with a stop for the ElectriCity bus. Here, safety aspects and new innovative solutions at the stop and interactions between vehicles and unprotected road users can be studied.<br /></p> <p><br /></p> <p>The fact that ElectriCity enters a new phase has already generated new research at Chalmers.<br /></p> <p><br /></p> <p>“One project about bus trains and one about autonomous docking at bus stops are just about to take off”, says Per Lövsund. “Another project investigates how bus drivers experience the effects of the Volvo Dynamic Steering system.”<br /></p> <p><br /></p> <p>A workshop is planned to be held at Chalmers to formulate projects on low-frequency noise in urban environment, modeling of noise impact and safety issues regarding quiet buses at bus stops.<br /></p> <p><br /></p> <p>“In the long run, perhaps other sectors could be included as well.

The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today’s technique. The obtained energy is a billion times higher than the energy of photons in visible light. These high intensity gamma rays significantly exceed all known limits and pave the way towards new fundamental studies.</b></p><p></p> <img width="120" height="156" class="chalmersPosition-FloatRight" alt="arkady140x182.jpg" src="/en/departments/physics/news/Documents/arkady140x182.jpg" style="margin:5px" />“When we exceed the limit of what is currently possible, we can see deeper into the basic elements of nature. We can dive into the deepest part of the atomic nuclei,” says Arkady Gonoskov, researcher at the Department of Physics at Chalmers University of Technology. <p></p> <p></p> The results were recently published in the high impact journal Physical Review X. The new method is an outcome of a collaboration between Chalmers University of Technology, Institute of Applied Physics and Lobachevsky University in Russia and University of Plymouth in the UK. Physicists in different fields, as well as computer scientists, have managed to work out the numerical models and analytic estimates for simulating these ultra-strong gamma rays in a new and somehow unexpected way. <p></p> In normal cases, if you shoot a laser pulse at an object, all the particles scatter. But if the laser light is intense enough and all parameters are right, the researchers have found that the particles are instead trapped. They form a cloud where particles of matter and antimatter are created and start to behave in a very special, unusual way. <p></p> <p></p> <span><img width="120" height="155" class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/F/Divisions/Condensed%20Matter%20Theory/Staff/Mattias-Marklund.png" alt="" style="margin:5px" /><span style="display:inline-block"></span></span>“The cloud of trapped particles efficiently converts the laser energy into cascades of high energy photons – a phenomena that is very fortunate. It’s an amazing thing that the photons from this source can be of such high energy,” says Mattias Marklund, professor at the Department of Physics at Chalmers. <p></p> The discovery is highly relevant for the future large scale laser facilities that are under development right now. The most intense light source on earth will be produced at such research facilities – as big as football fields. <p></p> “Our concept is already part of the experimental program proposed for one such facility: Exawatt Center for Extreme Light Studies (XCELS) in Russia. We still don’t know where these studies will lead us, but we know that there are yet things to be discovered within nuclear physics, for example new sources of energy. With fundamental studies, you can aim at something and end up discovering something completely different – which is more interesting and important,” says Arkady Gonoskov. <p></p> Text: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a><p></p> <a href="http://www.mynewsdesk.com/uk/chalmers/pressreleases/gamma-rays-will-reach-beyond-the-limits-of-light-2223060"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /></a>​ <strong>Read the scientific article</strong> <a href="https://journals.aps.org/prx/abstract/10.1103/PhysRevX.7.041003">Ultrabright GeV Photon Source via Controlled Electromagnetic Cascades in Laser-Dipole Waves</a> in Physical Review X.<p></p> <p><a href="http://www.mynewsdesk.com/uk/chalmers/pressreleases/gamma-rays-will-reach-beyond-the-limits-of-light-2223060"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release and download high-resolution images. ​</a></p> <h5 class="chalmersElement-H5">More information: </h5> <p></p> <a href="/sv/personal/Sidor/Mattias-Marklund.aspx">Mattias Marklund</a>, Professor, Department of Physics, Chalmers University of Technology, +46 31 772 39 39, mattias.marklund@chalmers.se <p></p> <p></p> <a href="/en/staff/Pages/arkady-gonoskov.aspx">Arkady Gonoskov</a>, researcher, Department of Physics, Chalmers University of Technology, +46 31 772 62 89, arkady.gonoskov@chalmers.se  <p></p> <strong>Further reading:</strong> <a href="/en/departments/physics/news/Pages/The-code-behind-a-breakthrough.aspx">The code behind a breakthrough in plasma physics.</a><p>​ </p>Thu, 19 Oct 2017 08:00:00 +0200https://www.chalmers.se/en/departments/tme/news/Pages/Electric-cars-can-become-more-eco-friendly-through-life-cycle-assessment.aspxhttps://www.chalmers.se/en/departments/tme/news/Pages/Electric-cars-can-become-more-eco-friendly-through-life-cycle-assessment.aspxElectric cars can become more eco-friendly through life cycle assessment<p><b>​It is time to stop discussing whether electric cars are good or bad.

However, imitating the solar energy process is a difficult task to achieve. Two young plasma physicists at Chalmers University of Technology have now taken us one step closer to a functional fusion reactor. Their model could lead to better methods for decelerating the runaway electrons, which could destroy a future reactor without warning.</b></p><div>​It takes high pressure and temperatures of about 150 million degrees to get atoms to combine. As if that was not enough, runaway electrons are wreaking havoc in the fusion reactors that are currently being developed. In the promising reactor type tokamak, unwanted electric fields could jeopardise the entire process. Electrons with extremely high energy can suddenly accelerate to speeds so high that they destroy the reactor wall. <br /> <br /></div> <div><span><img src="/SiteCollectionImages/Institutioner/F/340x296px/LinneaOla340x296IMG_0991.jpg" class="chalmersPosition-FloatRight" width="272" height="237" alt="" style="margin:5px" /></span>It is these runaway electrons that doctoral students Linnea Hesslow and Ola Embréus have successfully identified and decelerated. Together with their advisor, Professor Tünde Fülöp at the Chalmers Department of Physics, they have been able to show that it is possible to effectively decelerate runaway electrons by injecting so-called heavy ions in the form of gas or pellets. For example, neon or argon can be used as “brakes”. <br /><br />When the electrons collide with the high charge in the nuclei of the ions, they encounter resistance and lose speed. The many collisions make the speed controllable and enable the fusion process to continue.  Using mathematical descriptions and plasma simulations, it is possible to predict the electrons' energy – and how it changes under different conditions. </div> <div> </div> <div>“When we can effectively decelerate runaway electrons, we are one step closer to a functional fusion reactor. Considering there are so few options for solving the world's growing energy needs in a sustainable way, fusion energy is incredibly exciting since it takes its fuel from ordinary seawater,” says Linnea Hesslow. </div> <div> </div> <div>She and her colleagues recently had their article published in the reputed journal Physical Review Letters. The results have also attracted a great deal of attention in the field of research. In a short period of time, 24-year-old Linnea Hesslow and 25-year-old Ola Embréus have given lectures at a number of international conferences, including the prestigious and long-standing <a href="http://www.sherwoodtheory.org/index.php">Sherwood Fusion Theory Conference in Annapolis</a>, Maryland, USA, where they were the only presenters from Europe. </div> <div> </div> <div>“The interest in this work is enormous. The knowledge is needed for future, large-scale experiments and provides hope when it comes to solving difficult problems. We expect the work to make a big impact going forward,” says Professor Tünde Fülöp. </div> <div> </div> <div>Despite the great progress made in fusion energy research over the past fifty years, there is still no commercial fusion power plant in existence. Right now, all eyes are on the international research collaboration related to <a href="http://www.iter.org/">the ITER reactor in southern France.</a><br /><br /></div> <div>“Many believe it will work, but it's easier to travel to Mars than it is to achieve fusion. You could say that we are trying to harvest stars here on earth, and that can take time. It takes incredibly high temperatures, hotter than the center of the sun, for us to successfully achieve fusion here on earth. That's why I hope research is given the resources needed to solve the energy issue in time,” says Linnea Hesslow.<br /><br /></div> <div>Text and image: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a></div> <div> <img src="/SiteCollectionImages/Institutioner/F/750x340/fusionsreaktor_image_EUROfusion750x340.jpg" alt="" style="margin:5px" /><br /><span>Although the vacuum chamber in the British fusion reactor JET has a wall made of solid metal, it can melt if it gets hit by a beam of runaway electrons.

The energy is created the same way as in the sun, and the process can also be called hydrogen power. Fusion power is a much safer alternative than nuclear power, which is based on the splitting (fission) of heavy atoms. If something goes wrong in a fusion reactor, the entire process stops and it grows cold. Unlike with a nuclear accident, there is no risk of the surrounding environment being affected. The fuel in a fusion reactor weighs no more than a stamp, and the raw materials come from ordinary seawater. </div> <div>As yet, fusion reactors have not been able to produce more energy than they are supplied. There is also a problem with so-called runaway electrons. The most common method of preventing this damage is to inject heavy ions, such as argon or neon, which act like brakes due to their large charge. A new model developed by researchers at Chalmers describes how much the electrons are decelerated, paving the way to making these runaway electrons harmless.  <br /><br /></div> <div>Read the scientific article <a href="https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.118.255001">“Effect of partially-screened nuclei on fast-electron dynamics&quot;</a>.<br /></div> <div>  <br /></div> <div>The article was written by Linnea Hesslow, Ola Embréus, Adam Stahl, Timothy DuBois, Sarah Newton and Tünde Fülöp of the Department of Physics at Chalmers University of Technology, and Gergely Papp of the Max Planck Institute for Plasma Physics in Garching, Germany. <br /></div> <h3 class="chalmersElement-H3">More information: <br /></h3> <div><span><a href="/en/Staff/Pages/hesslow.aspx"><strong><span><strong>Linnea Hesslow</strong></span></strong><span></span></a>,</span> PhD Student, Department of Physics, Chalmers University of Technology, +46 70 519 41 67, hesslow@chalmers.se</div> <div><strong><a href="/en/staff/Pages/embreus.aspx">Ola Embréus</a></strong>, PhD Student, Department of Physics, Chalmers University of Technology, +46 73 052 80 70, embreus@chalmers.se</div> <div><strong><span><a href="/en/Staff/Pages/Tünde-Fülöp.aspx">Tünde Fülöp</a></span></strong>, Professor, Department of Physics, Chalmers University of Technology, +46 72 986 74 40, tunde.fulop@chalmers.se<br /><br /><a href="http://www.mynewsdesk.com/uk/chalmers/pressreleases/deceleration-of-runaway-electrons-paves-the-way-for-fusion-power-2023834"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release and download high resolution images. </a><br /></div>Tue, 20 Jun 2017 00:00:00 +0200
