摘要
为检测SC200质子医疗加速器引出束流质量,在引出参考点对加速器引出束流进行检测,实现对加速器性能的验收。该文主要介绍一种在加速器引出参考点采用荧光靶实现束团位置及截面尺寸的检测,采用基于皮安表的法拉第筒实现束流流强2.5级精度检测的设计。基于LabVIEW虚拟机及PLC可编程控制器实现束测探针的远程控制及信号采集与处理。
In order to detect the beam quality of the SC200 superconducting cyclotron, measure the beam at the extraction reference and the acceptance of the accelerator is realized. This article mainly introduces the design that use the scintillation screen at the extraction reference to measure the beam profile, position and use the Faraday cup to measure the current intensity with 2.5 level accuracy. The remoted controlling of probes and the acquisition and processing of signal based on LabVIEW and PLC.
