这篇论文是一篇教程级别的综述，涵盖了与带电粒子束电流测量相关的广泛方面。本教程首先介绍作为信号源的束流特性、相关电磁场、典型加速器环境对这些场的影响，以及修改和控制该环境以便于束流测量的常用方法。简要介绍了三种不同类型的电流监测器，并对经典互感器电路进行了定量的评述。认识到环境噪声拾取在定量测量中可能是一个很大的误差来源，使用真实的例子对信号处理考虑给予了相当大的关注。给出了一个成功的传输线束流监测器实施的例子，本教程最后对信号处理和电流监测器校准问题提出了一些意见。
This paper is a tutorial level review covering a wide range of aspects related to charged particle beam current measurement. The tutorial begins with a look at the characteristics of the beam as a signal source, the associated electromagnetic fields, the influence of the typical accelerator environment on those fields, and the usual means of modifying and controlling that environment to facilitate beam current measurement. Short descriptions of three quite different types of current monitors are presented and a quantitative review of the classical transformer circuit is given. Recognizing that environmental noise pick-up may present a large source of error in quantitative measurements, signal handling considerations are given considerable attention using real-life examples. An example of a successful transport line beam current monitor implementation is presented and the tutorial concludes with a few comments about signal processing and current monitor calibration issues.
