Description
To realize the saturation output of Beijing Free Electron Laser (BFEL), the phase stability of RF power in accelerator is required to be less than +- 1 degree. The relations between RF phase variation and the Pulse Form Net (PFN) in modulator of klystron are carefully studied through experiments. In order to meet the requirement of RF phase stability, all 48 sets of the PFN in HV modulator are repeatedly adjusted to obtain optimum result. In the pulse width of 6μs, RF phase ripple from the output of klystron is reduced to +-1.5 degree from +-2.6 degree before the adjustment; In the pulse width of 4μs, practically used in BFEL, RF phase ripple is only +- 1 degree
