Development of a real-time monitoring and data acquisition system for the stable operation of high-temperature superconductor magnets

High-temperature superconductor (HTS) magnets for booster synchrotrons with rapid ramping capability and for use as strong light sources (undulators and wigglers) are emerging as key next-generation technologies that can significantly enhance the performance of particle accelerators. They are vulnerable to rapid environmental changes, which can cause a quench and result in severe damage to the magnets and the entire system. Therefore, it is essential to monitor key physical parameters-such as current, voltage, and temperature-in real time with high speed and precision, enabling early detection of anomalies and prevention of system. In this study, we developed a data acquisition system based on the DT9824 module to replace the discontinued SCXI-1125 module. The proposed system is built based on Python and EPICS, without relying on commercial software, offering high flexibility, user configurability, and suitability for automated measurement environments. We have successfully conducted simultaneous acquisition of 32 channels using eight DT9824 modules, and long-term stability tests are underway.
