Abstract :
The electron injector for the SLAC Linear Coherent Light Source (LCLS) must produce a low jitter, high brightness beam. This beam must be accelerated and longitudinally compressed to yield a sub-picosecond beam which radiates a burst of, self-amplified spontaneous emission X-rays upon passing through a long undulator. As the gain of this amplifier is very sensitive to the emittance, energy spread and peak current the electron source and subsequent transport, acceleration, and compression systems must reproducibly give a very high quality beam. The conceptual design of an RF photocathode gun which satisfies the requirements of the LCLS is presented here
