Description
AWAKE is constructing a new electron injector for external injection for Run 2C. One of the main goals of the experiment is to demonstrate external injection into a plasma wake field and emittance and energy spread control during acceleration. The injector consists of an S-band high gradient RF-gun and high-gradient X-band accelerating structures for velocity bunching and acceleration. The nominal beam has a bunch charge of 100 pC, a bunch length of 200 fs and an emittance below 2 um. This beam has to be focused down to 6 um in order fulfil the matching conditions during plasma acceleration. Additional requirements are a very good energy stability, a small energy spread and low longitudinal and transverse jitter. The status of this injector and its key-hardware will be presented.
