Accelerator safety interlock system for proton therapy

Abstract

The invention discloses an accelerator safety interlock system for proton therapy. The accelerator safety interlock system for proton therapy comprises an upper computer PC, a switch, a PLC, a photoelectric conversion module and each subsystem of the accelerator; the upper computer PC is used for remotely monitoring and operating the state and operation of the accelerator subsystems, setting permissions and switching different modes at the same time, so as to facilitate the launching and debugging of the accelerator; the photoelectric conversion module converts an optical fiber signal into anelectrical signal that can be used by the PLC; each subsystem of the accelerator comprises a water cooling system, a lifting system, a superconducting magnet system, a vacuum system, an ion source system, an RF system and a lead-out zone system. The invention has the beneficial effects that: the hardware use and differentiation of the accelerator safety interlock system is very detailed, and is convenient to use; the system accelerator safety interlock system responds faster; and the accelerator safety interlock system is easier to use and operate, and has higher working precision.

Description

technical field [0001] The invention belongs to the field of accelerator equipment safety, and relates to a safety interlock system, in particular to an accelerator safety interlock system for proton therapy. Background technique [0002] At present, accelerators have been widely used in many industries, especially in the field of proton therapy, where accelerators are used to accelerate protons. The protons are accelerated in the gap of the drift tube, and after entering the drift tube, the protons are protected from the influence of the decelerating electric field, which improves the quality and efficiency of proton therapy. [0003] The interlock protection of accelerator equipment also adopts different methods and technical means. Most of them incorporate the safety interlock system into the control system, use the same interface to display and integrate data collection; there are also a few that separate the safety interlock system from the control system. , using diff...

[0003] The interlock protection of accelerator equipment also adopts different methods and technical means. Most of them incorporate the safety interlock system into the control system, use the same interface to display and integrate data collection; there are also a few that separate the safety interlock system from the control system. , using different interfaces, but the hardware is not distinguished in detail, which increases the complexity of the safety interlock system and the amount of data processing, and cannot meet the requirements of response time. In order to solve the above defects, a solution is now provided
