Abstract

Electron pulses for the Northrop Grumman Compact Free Electron Laser CIRFEL are produced at a repetition rate of up to 10 Hz by the illumination of a Mg photocathode with a photon injector 261 nm seed laser system mode locked to the 20th sub-harmonic of 2.856 GHz. Presently the system is being operated in the 10 to 12 MeV energy range and spontaneous radiation has been observed. We present some preliminary results on electron beam characterization including its energy spread, energy stability, and spontaneous radiation observations
