【Abstract】 In order to compensate the RF phase drift due to various factors, we will establish a RF phasing system for BEPCⅡ linac. Energy maximizing method will be used to determine the RF phase of each RF power source. A coaxial line will be used to distribute RF phase reference along the klystron gallery. The key components, such as PAD unit, IA units, have been developed. A minimum phasing system is established and runs successfully.更多还原
