The stability of the RF phase in the LINAC of SuperKEKB is affected by the high voltage of the klystron and the temperature of the cooling water in the accelerating structure. To improve the stability of the RF phase, a new RF signal is generated by the RF gun's laser source, which is synchronized with a 2856 MHz signal. The laser output is transmitted through a free space area to sector B and detected by a photodetector, which is not impacted by temperature fluctuations or klystron interference.
