Abstract
We discuss the design and performance of a 2 to 4 nm FEL operating in Self-Amplified Spontaneous Emission (SASE), using a photoinjector to p roduce the electron beam, and the SLAC linac to accelerate it to an en ergy of about 7 GeV. Longitudinal bunch compression is used to increas e the peak current to 2.5 kA, while reducing the bunch length to about 40 mum. The FEL field gain length is about 6 m, and the saturation le ngth is about 60 m. The saturated output power is about 10 GW, corresp onding to about 10(14) photons in a single pulse in a bandwidth of abo ut 0.1%, with a pulse duration of 0.16 ps. Length compression, emittan ce control, phase stability, FEL design criteria, and parameter tolera nces are discussed.
