Development and Validation of Lattice Adjustment Application Based on PACS under DC/Pulse Dual-mode

  • 摘要: 目前,中国科学院近代物理研究所设计、建造和运维了多台结构指标各异的重离子加速器装置,现有的物理控制系统已无法满足这些装置对于稳定、可靠、高效运行的需求。为了提高调试、运行效率,简化系统操作,达到更高的流强和更好的束流品质,中国科学院近代物理研究所自主设计了一套基于EPICS的面向物理的加速器控制系统PACS。为了验证PACS框架的可行性和嵌入任意物理控制软件的可行性,采用Python语言开发了基于PACS的直流/脉冲双模式工作点调节软件及其界面,并且搭建了HIRFL-CSRe的MySQL测试数据库和EPICS软IOC测试环境,在该虚拟测试环境下对软件的直流模式下工作点调节功能进行了测试;然后在HIRFL-CSR真实环境对该软件在直流/脉冲模式下的工作点调节功能进行测试。结果表明,该软件能够通过PACS提供的接口嵌入系统的物理过程模块,实现与数据库和底层控制系统的交互,从而完成直流/脉冲模式下的工作点调节和光学参数计算,以此验证PACS框架的可行性和嵌入任意物理控制软件的可行性。

     

    Abstract: To reduce the amount of duplication efforts of physical and program developers, a portable, extensible and maintainable PACS (Physics-oriented Accelerator Control System) is proposed and implemented for heavy ion accelerator facilities by IMP (Institute of Modern Physics, Chinese Academy of Sciences). For testing the feasibility of the PACS, a lattice adjustment application and its new GUI for both DC and pulse modes is programmed by Python language. The DC mode, built with the SQL database and soft IOC of the EPICS, is performed in the HIRFL-CSRe. In addition, the pulse mode is tested in the HIRFL-CSRm. The testing results show that the tune adjustment and optics calculation in the two modes are implemented successfully, and the PACS can provide the interfaces between the modules and layers. Therefore, the framework of the PACS is feasible.
