Description
AWAKE studies and develops a plasma wakefield accelerator driven by a long proton bunch to produce high-energy electrons for application to particle physics at CERN. It relies on the self-modulation of a cm-long, 400GeV proton bunch to reach ~1GV/m accelerating fields. It is also a platform to study beam-plasma interactions. I will introduce the project and experiment. I will show experimental results on: Seeding of self-modulation; Observation of the growth of self-modulation; Observation of the effect of motion of plasma ions; Acceleration of externally-injected test electrons; Observation and seeding of the hose instability; And observation of the transverse filamentation instability. I will outline plans for upcoming experiments aimed at transitioning from acceleration experiments to an accelerator for applications. These open new opportunities, for example in terms of development of long plasma sources (50-100m), diagnostics and other key components of the accelerator.
