超长周期慢引出主环磁铁电源控制系统设计

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

介绍了兰州重离子加速器冷却储存环(HIRFL-CSR)超长周期慢引出主环(CSRm)磁铁电源控制系统的设计。该系统采用基于高速以太网的分布式控制系统,选用了ARM+DSP结构的前端智能控制器,对整个运行周期的控制采用了分段处理的机制,解决了波形数据量过大而无法在前端控制器进行全波形存储的问题。该系统已经在加速器冷却储存环中通过了调试,满足了物理实验的要求。

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 ion＇s ten-thousand-second slow extraction.
