闭轨畸变对合肥同步光源的束流质量产生负面影响,因此必须对闭轨畸变进行校正。本文介绍了基于MATLAB的合肥光源储存环束流轨道校正系统的工作原理、开发过程及测试结果。该系统由束流轨道测量系统、校正铁系统和控制系统组成,基于MATLAB开发的束流轨道校正程序运行于操作员界面工作站上。首先对获取的束流轨道数据进行分析和计算,然后通过控制系统改变校正铁电源的电流以改变校正铁磁场强度,从而实现轨道校正。测试结果表明:束流轨道的最大畸变由校正前的4.468 mm下降到校正后的0.299 mm;标准方差(SDEV)由校正前的2.986 mm下降到校正后的0.087 mm。该系统达到了设计目标。
The closed-track distortion has a negative impact on the beam quality of the Hefei synchronous light source, so the closed-track distortion must be corrected. This paper introduces the working principle, development process and test results of Hefei light source storage ring beam trajectory correction system based on MATLAB. The system consists of a beam trajectory measurement system, a correction iron system and a control system. The beam trajectory correction program developed based on MATLAB runs on the operator interface workstation. Firstly, the acquired orbit data is analyzed and calculated, and then the current is corrected by the control system to change the intensity of the correction ferromagnetic field, so that the orbit correction can be achieved. The test results show that the maximum distortion of the beam orbit decreases from 4.468 mm before correction to 0.299 mm after correction, and the standard deviation (SDEV) decreases from 2.986 mm before correction to 0.087 mm after correction. The system has achieved its design goals.
