Abstract：
This control system is used to flatten the flat-top of the amplitude and phase macro-pulses of the high power klystron output.This is of critical importance in improving the electron beam quality for FEL and other applications. The self-adaptive feed-forward control system is adopted to stabilize the RF power supply for the LINAC, which utilizes linearization and matrix algebra to simplify the computation. The system is operational and some experimental results have been obtained, which demonstrate that the system is effective to improve the beam quality.
