摘要：
Background: The Shanghai high repetition rate XFEL and extreme light facility (SHINE) accelerates electrons up to 8 GeV using cryogenic-superconducting high-frequency cavity. Wire scanner system is applied to the beam profile measurement of SHINE due to its advantages such as fewer secondary particles generation compared with that of complete beam block, hence reduce the risk of superconducting cavity. Purpose: This study aims to design data acquisition system for wire scanner system and realize synchronous acquisition of beam loss signal and relative position between the wire and beam. Methods: The data acquisition system for wire scanner was designed to include radio frequency (RF) daughter board with analog signal digitizer, digital motherboard, firmware, data processing software. A Zynq-UltraScale+ based system on chip (SoC) was employed as system central component, and a field programmable gate array (FPGA) was used for system control and data transmission whilst the advanced RISC machine (ARM) integrating Linux was implemented for data acquisition and communication. Finally, experimental test of this data acquisition system was performed on the testbed to verify its feasibility and functionalities. Results: The data acquisition system can correctly read back position of grating ruler, and achieve synchronous acquisition of sample beam loss signal and signal of cavity beam position monitor. Conclusions: The data acquisition system meets the requirements of SHINE wire scanner system. It will be applied to the prototype of SHINE wire scanner system. © 2022, Science Press.
