Classical Resistivity Method in Atmosphere and Vacuum

Shigeyuki Takahashi

Abstract

In the space industry one of the most serious problems is charge storage on spacecrafts caused by plasma, solar-photo-emission that causes damage to the spacecrafts. Therefore, the research by government and industry about spacecraft charging is thriving because there are still plenty of unknown faces in the space. A key first step for research of the phenomenon in ground-based laboratory test is to know well the most suitable experimental methods for measuring resistivity of spacecraft materials.

This talk describes my investigations of the Classical Resistivity (constant voltage capacitor) Method to measure resistivity. I concentrate on understanding the differences between tests done in atmosphere and vacuum.
