摘要

南京大学研制的20MeV电子直线加速器无阻拦束流监测系统，采用高导磁率软磁铁氧体磁芯、配以前置放大器，脉冲选通器和束流积分器。磁芯的次级绕组匝间加阻尼电阻抑制谐振，抗干扰能力强，用于在线监测平均流强和累积电荷量。可按预置值与加速器出束系统联锁，并给出信号实现束流强度自动控制（AIC）。系统量程较宽，可测量20mA-2A脉冲束流。实验结果表明，该系统输出线性较好，波形畸变小，测量精度可达±5%以内。

Abstract

A non-intercepting beam monitor system for the 20 MeV linear electron accelerator at Nanjing University was developed. The system includes some magnetic cores

a preamplifier

a pulse selector and a beam integrator.

The experimental results have indicated that the system has good linearity with low distortion of waveform. The precision of measurement is better than ±5%.
