Design and Implementation of a SoC Embedded Waveform Acquisition System for Surveillance and Diagnostics of Pulsed Magnet Power Supplies

Pulsed magnet power supply systems used for electron beam injection and extraction have been developed for the Taiwan Photon Source (TPS) and the Taiwan Light Source (TLS). Control systems for these supplies have been implemented with well-functioning operations interfaces. To accomplish higher reliable operation, advanced real-time diagnostic toolkits for pulsed magnet power supplies had to be developed. A SoC (System-on-Chip) embedded waveform acquisition system has been designed, implemented and applied to inspect pulsed magnet power supplies during routine operation. This waveform acquisition system not only operates at the 125 MS/s sample rate, 50 MHz bandwidth and 14 bits resolution, but supports also the EPICS software framework for complete system integration. The acquired current waveforms can be immediately extracted specific characteristics to examine the status of pulsed magnet power supplies. In this paper, we summarize the design, implementation and real-time data analysis of the SoC embedded waveform acquisition system for the pulsed magnet power supplies.
