Paper Abstract

For high power free electron laser applications, such as power beaming, the electron accelerator must deliver a bright electron beam at high average current. The excellent beam brightness of the RF photoinjector is well established, however, until recently none has operated with an average current above 10 microamperes. This paper describes the operation of a RF photoinjector from 20 to 32 milliamperes of average current. The electron beam emittance dependence upon micropulse charge and the photocathode quantum efficiencies and operating lifetimes obtained during high duty factor testing are discussed.
