摘要

介绍了一种用于监测航天器表面和内部电荷效应的新型仪器。该仪器的目的是提供一种可靠的诊断工具，可以在长期运行的卫星上飞行，因为严重的质量、功率和容纳限制通常阻止安装更复杂的设备。简要回顾了充电对航天器的危害，然后描述了仪器的基本设计，其中设置了绝缘材料充电的电气模拟装置。采用超高值电阻(高达10/sup 14/ /spl Omega/)来模拟电介质的特性。电子束充电试验的结果证明了该方法的有效性。

A compact electrostatic charging monitor for spacecraft

A new instrument for monitoring both surface and internal charging effects on-board a spacecraft is described. The aim of the instrument is to provide a reliable diagnostic tool that can be flown on long-life operational satellites where severe mass, power and accommodation restrictions usually prevent the installation of more complex devices. A brief review of the charging hazard to spacecraft is provided followed by a description of the instrument's basic design in which electrical analogues of the charging of insulating materials are set up. Ultra-high-value resistors (up to 10/sup 14/ /spl Omega/) are employed in order to simulate the properties of a dielectric. Results from electron beam charging tests are provided which demonstrate the validity of the approach.
