| Abstract: | Sub-sampling technology has been adopted to realize fully-digitalized beam phase measurement electronics system for linac in China Spallation Neutron Source(CSNS). This paper introduces measurement principle and operation procedure of the system and describes analog signal processing, sampling and frequency module. It also presents the experimental results of measuring 324 MHz/100 mVpp sine wave, which achieves phase resolution less than 0.1 and non-uniformity between channels limited in 0.2, satisfying the requirements of system. |
