静电分析仪（ESA）用于电力推进，测量离子束和电子束的单位电荷能量/分布，例如在推进器的下游区域。本文概述了最基本的，但最广泛使用的ESA设计类型。分析仪分为两类：（1）反射镜型分析仪和（2）偏转器型分析仪。常见的镜型分析仪是平行板镜分析仪（PMA）和柱面镜分析仪（CMA）。对于偏转器型分析器，首先描述了广义的环形类型，并作为特例讨论了常用的圆柱偏转器（CDA）和球形偏转器（SDA）分析器。描述了ESA能量分辨率计算的程序，这是比较分析仪的常用方法。最后，我们提出了离子的能量分布从SDA，比较粒子能量，粒子角度，入口和出口的几何形状，和扇区角度使用数值计算和粒子模拟的变化。
Electrostatic analyzers (ESAs) are used in electric propulsion to measure the energy per unit charge ⁄ distribution of ion and electron beams, in the downstream region of thrusters for example. This paper serves to give an overview of the most fundamental, yet most widely used, types of ESA designs. Analyzers are grouped into two classifications: (1) mirror-type analyzers and (2) deflector-type analyzers. Common mirror- type analyzers are the parallel-plate mirror analyzer (PMA) and the cylindrical mirror analyzer (CMA). For deflector type analyzers, a generalized toroidal type is first described and the commonly used cylindrical deflector (CDA) and spherical deflector (SDA) analyzers are discussed as special cases. The procedure for energy resolution calculations of ESAs is described, which is a common way of comparing analyzers. Finally, we present ion energy distributions from a SDA, comparing variations in particle energy, particle angle, entrance and exit geometry, and sector angle using both numerical calculation and particle simulation.
