Abstract：
A new method of arbitrary variation of the phase of RF system during the macropulse to optimize the FEL output is proposed. In this method, the FEL output is used as a tuning indicator to adjust the RF phase in different time intervals of the macro pulse with computer controlled arbitrary function generator. In this case, shortest build up time and largest saturated power in a macro pulse can be simultaneously achieved. Experimental testing of this method has been carried out in Beijing IR FEL oscillator and proves to be effective in increasing the power output of BFEL facility.
