Phase Space Control of Ion Acceleration in Laser-plasma Interactions
Seminar by Luis O. Silva, GoLP/Instituto de Plasmas e Fusão Nuclear, Instituto Superior Técnico, Universidade de Lisboa, Portugal
Abstract of talk
I will review some of the possible ion acceleration mechanisms and how it is possible to control the phase space dynamics of ions accelerated in the context of high intensity laser-plasma interactions. I will first address ion acceleration in clusters, including the transition from hydrodynamic expansion to cluster explosions and the control of these explosions. I will then consider the possibility to excite collisionless shocks and the relevance of these shocks for ion acceleration and how it is possible to probe the transition between the different ion acceleration regimes by properly tailoring the properties of the targets. Finally I will address the ion acceleration in vacuum using laser with an emphasis on isotope separation and acceleration of particles with very short lifetimes.
