一种非拦截式束流强度测量方法的研究

 介绍了用圆柱型容性感应探针进行非拦截式束流强度测量的方法。该方法利用测量束流相宽和中心相位的感应探针同时进行束流强度的监测, 以满足HIRFL束流诊断的在线测控要求；说明了采用数字示波器测量束流感应信号并从中提取束团相宽及束流强度等信息的原理。介绍了测量系统装置及虚拟仪器技术在本系统中的应用，并给出了初步实验结果和测量精度的分析。

A NON-INTERCEPTIVE MEASUREMENT METHOD OF BEAM INTENSITY

This paper introduces one non-interceptive beam intensity measurement by using a cylindrically capacitive which is originally used for the measurements of beam bunch length and central phase. The induced signal from the probe now is used for measuring simultaneously all the three beam characteristics for around m A heavy ions at HIRFL accelerator complex. The measurement principle for beam intensity and the system structure are presented. Applying the technique of virtual instruments to the system is described briefly. The preliminary experimental results are also given.
