摘要

华中科技大学正在利用240 MeV超导回旋加速器建设质子治疗设施（HUST-PTF）。为了控制光束传输过程中与光束线相关的器件，提出了一种基于开放平台通信统一架构（OPC UA）的分布式光束线控制系统（BCS）。在上一个版本的BCS中，存在线程阻塞、数据刷新率低、功能缺陷等问题。为了克服上述缺点，本研究通过线程流优化和选择性监控机制优化磁体电源与BCS之间的交互，引入非规范化波束数据库，并将波束诊断子系统集成到BCS中。最后，改进后的BCS在不同能量设置下的质子束现场验证，证明成功地遵守了设计要求。

Improved HUST-PTF beamline control system for beam commissioning

Huazhong University of Science and Technology is constructing a proton therapy facility (HUST-PTF) utilizing a 240 MeV superconducting cyclotron. To control the beamline-related devices during beam transportation, a beamline control system (BCS) with a distributed architecture based on open platform communications unified architecture (OPC UA) was proposed. In the last version of BCS, there are some issues, such as thread blocking, low data refresh rate, and functional deficit. To overcome the mentioned drawbacks, this study optimizes the interaction between magnet power supplies and the BCS through thread flow optimization and a selective Monitor mechanism, introduces a denormalized beam database, and integrates the beam diagnostics subsystem into BCS. Finally, the improved BCS is validated on-site with a proton beam under different energy settings, demonstrating successful adherence to the design requirements.
