Abstract :
A new RF control system was designed and implemented to support short pulse High Gain Harmonic Generation (HGHG) experiments, which require subpicosecond synchronization between the laser and the accelerating RF fields. This control system consists of a 81 MHz crystal oscillator to drive both the Ti::Sapphire laser and a 2856 MHz synthesizer, direct vector modulators that control the amplitude and phase of the klystron drive and vector de-modulators for amplitude and phase measurement. RF and electron beam based measurement results of the RF to laser jitter are presented as well as experimental results of synthesizing the RF directly from the 81.6 MHz pump laser pulse train.
