Latest Results on Plasma Wakefield Acceleration

A dense, ultra-relativistic electron bunch propagating through a uniform plasma can produce a highly nonlinear wake that can be employed for accelerating a second, trailing bunch in a scheme known as the Plasma Wakefield Accelerator (PWFA). Recent work has shown that a PWFA cavity can accelerate a low energy spread electron bunch containing a significant charge at both high gradients and high energy-extraction efficiency - necessary conditions for making future particle accelerators both compact and less expensive. In addition to this, the next important issues that must be addressed are the generation, acceleration and extraction of ultra-low emittance bunches from plasma accelerators. Such bunches are ultimately essential to obtaining extremely bright beams for future light sources and high-luminosities for future particle colliders. A new facility, FACET II is being constructed at SLAC that will enable the demonstration of a single electron stage of a future multi-stage plasma wakefield collider. I will describe the plans and the progress for the upcoming experimental campaign on FACET II.
