abstract:	A photoinjector is being constructed in order to produce a pulse train of up to 800 electron bunches, each with 8 nC of charge and a 3.5 ps rms bunch length. The spacing between bunches within a train is 1 s and the train repetition rate is 1?10 Hz. The desired transverse emittance is <20 mm mrad. An rf photo-gun delivers a bunched 4?5 MeV beam which will be accelerated to 14?18 MeV by a 9- cell superconducting cavity and compressed magnetically. Measurements have been done on the beam delivered by a first prototype rf gun; installation of a new rf gun, the 9-cell cavity, and the bunch compressor is in progress.
