摘要

介绍了偏压电荷收集器的结构

分析了利用其测量HPIB束流强度的原理

利用KARAT PIC软件模拟了偏压电荷收集器内部的电荷输运过程

模拟结果表明HPIB在偏压电荷收集器内部电荷中和而电流不中和

从而证实了电荷中和假设和这种装置测量HPIB的准确性。另外还分别对几何参数和偏置电压对偏压电荷收集器的影响进行了模拟

在德拜长度范围内

孔径的大小为0.6-0.8 mm比较合适

偏压为-800 V就可满足峰值能量为500keV HPIB的测量要求

实验验证了偏压大小与离子收集效率之间的关系。

Abstract

Structure of the biased charge collector for measuring HPIB is introduced in this paper. The inner charge propagation process of HPIB in the biased charge collector was simulated with KARAT PIC code. The simulation results indicated that charge was neutralized but current was not neutralized in the biased charge collector. The influence of biased voltage and aperture diameter were also simulated. A -800 V biased voltage can meet the requirement for measuring 500 keV HPIB

and this is consistent with the experimental results.
