Description
This report presents the development and validation of a high-speed data acquisition system for Gas Monitor Detectors at the Shenzhen Superconducting Soft X-ray Free-Electron Laser (S3FEL). The system is designed to support real-time, pulse-by-pulse monitoring of photon intensity and beam position across six beamlines operating at up to 1 MHz repetition rate. Based on the MTCA.4 platform, the DAQ integrates custom front-end electronics with an AMC digitizer featuring four-channel 1 GSPS sampling and 14-bit resolution. Key innovations include dual-redundant fiber timing synchronization, PCIe-based real-time data streaming, and EPICS-integrated slow control. Preliminary tests confirm ADC linearity, low timing jitter, and sustained PCIe throughput, demonstrating the system’s readiness for deployment in MHz-class FEL facilities.
