Abstract of talk
High energy colliders used for research on the nature of matter and forces, have become gargantuan and very expensive to build. New techniques that will reduce the cost and size of these machines are therefore being pursued. In this talk I will discuss the latest progress on electron and positron beam-driven wakefield acceleration in performed plasmas and hollow plasma channels. Both linear and extremely nonlinear regimes of plasma wakefield acceleration have been studied. The electric field structure of the wakefield cavity have been mapped out with extraordinary accuracy and shows that the cavity field structure is indeed suitable for accelerating electrons with minimal emittance growth. First data on emittance of ionization injected electrons into such wakes will be presented that shows that the emittance of the accelerated particles can be more than an order of magnitude smaller than that of the drive bunch that excites the wake. I will then discuss the long range plans for PWFA research in the US.
