Magnet power supply control system for CSRm super-long-period slow extraction

In order to realize the HIRFL-CSR super-long-period slow extraction, the distributed control system of the CSR main ring(CSRm) power supply is designed based on high-speed Ethernet, with the controller of the power supply employing ARM+DSP architecture. The control cycle adopts multipart handling mechanism to solve the problem that the waveform data is too large to be stored in the controller. The control system has been tested in the HIRFL-CSR, and successfully conducted the carbon ions ten-thousand-second slow extraction.
