Abstract

We present initial results of performance testing of the RF power system built for the Rocketdyne Free Electron Laser program. The RF power system consists of a SLAC 5045 klystron powered by a modulator unit built by the Beta Division of the Titan Corporation. The system is capable of providing 65 MW, 3.5 μsec macropulses at 180 pps and employs innovative feedback and feed-forward control techniques in order to achieve amplitude flatness and phase stability. Preliminary rf amplitude, pulse flatness and phase stability measurements indicate phase stability better than ±1° and pulse flatness better than ±0.25% are achievable at the 65 MW operating point
