    摘要:

    医用回旋加速器目前广泛应用于国防基础科学研究、同位素生产以及诊断、治疗等应用领域,然而都无一例外地要求其稳定性、安全性。本文从医用回旋加速器的应用需求出发,概述了控制系统的组成、各子系统的作用,详细阐述了以RX3i可编程控制器为前端控制器的系统集成、高频系统的低电平控制的控制策略以及不同工作模式下各系统间的安全联锁。连续的运行结果表明:控制系统保证了整个系统的平稳运行,满足了加速器运行及其调试要求。

    Abstract:

    Medical cyclotron is widely used in the fields of national defense basic science research, isotope production, diagnosis and treatment. High stability and security of medical cyclotron system are required in these situations. Based on these application requirements, this paper outlines the composition of the control system, briefly introduces the role of each subsystem, and finally the system integration with RX3i programmable controller as the front-end controller, the control strategy of low-level control of high frequency system and the security interlock of each system under different working modes are elaborated in detail. The results of continuous operation show that the control system ensures the stable operation of the whole system and meets the requirements of accelerator operation and debugging.
