Abstract
We present here a conceptual design for an X-ray FEL operating at 45 /spl Aring/and producing 0.1-1.0 GW of power. Its architecture is a single-pass amplifier with growth from spontaneous noise. It uses an electron beam of about 1.5 GeV and with a normalized emittance of about 20 mm mrad, a beam which may be accelerated in a relatively short length of a high-gradient accelerator driven by an X-band relativistic klystron. Examination of sensitivity of the FEL performance to energy spread, wiggler field errors, jitter in the positioning of the electron beam, and finite steering accuracy indicates that the requisite technologies for this design are imminently available.
