Development of Control System for CSNS RF Driven Ion Source

    摘要
  • 摘要: 为满足中国散裂中子源打靶功率提升需求，加速器采用外置天线射频负氢离子源替换此前使用的潘宁表面负氢离子源，为加速器提供高品质和高稳定的束流。文章主要介绍了基于EPICS软件系统和PLC硬件平台的射频负氢离子源控制系统设计方案和具体实现。针对射频功率源的电磁干扰和高压平台打火造成设备损坏，给出了相应的解决措施。此外，为提高离子源长期运行稳定性，设计了放电室高精度注铯控制程序及打靶功率稳定程序。控制系统自投入运行以来，运行稳定可靠，为离子源的高效运行提供了有力保障。

     

    Abstract: The China Spallation Neutron Source(CSNS) has experienced a growing demand for increased beam power, necessitating the replacement of their previous Panning H-ion source with an external antenna RF driven H-ion source. This paper outlines the design and implementation of the control system for this new ion source based on EPICS and PLC. To ensure a stable and reliable operation, solutions were developed to optimize to optimize electromagnetic interference and prevent equipment damage caused by high voltage platform ignition. Additionally, operational assistance programs were designed to improve the long-term stability of the ion source. The control system has been successfully implemented, it has been stable and reliable, providing strong support for the efficient operation of the ion source.
