High-brightness racetrack microtron injector

Our RaceTrack Microtron will produce electron beams with energies up to 35 MeV, /spl sim/5 mm/spl times/mrad normalized emittance, bunch charge in excess of 150 pC, and rates up to 150 Hz. Its 5 MeV injector consists of a 1.6 MeV Radio-Frequency laser stimulated photocathode electron gun and a 3.4 MeV linac. We describe the injector and RF-system performance, as well as the beam diagnostics.
