Abstract: X-ray beam position Monitor (XBPM) can be used to measure the position of synchrotron radiation. The front-end acquisition circuit is mainly used for analog signal acquisition and processing. In this paper, an XBPM electronic analog front-end board (XBPM-AFE) suitable for the front end area of High Energy Photo Source (HEPS) beamline is developed. The functions of current-voltage conversion, range switching, gain control and ADC sampling of the signal of XBPM are designed and implemented. The hardware circuit design and the test results of XBPM-AFE are given.
