Abstract：
One of the crucial factors for the beam quality of photocathode RF gun is the relative timing jitter between the laser pulse and the RF phase. This paper introduces the sub-picosecond timing jitter measurement and the feedback control technologies, analyzing beam quality influence caused by the jitter, and acquired practical experience for using a PLL to reduce the laser pulse's phase noise, so as to solve the synchronization problem between the laser beam and the RF phase in the photocathode RF gun.
