Electric Field Observations of Time Constants Related to Charging and Charge Neutralization Processes in the Ionosphere
The accumulation and neutralization of charge in space plasmas has been a subject of interest for many years. Spacecraft charging has been the topic of special conferences (see Finks and Pike, 1979) and a dedicated satellite mission (SCATHA). Charge separation or regions of excess change become a source of electric fields, often of a transient nature, in the plasma medium. Also, vehicles in space that emit charged particles must be neutralized by current from the plasma medium. The charging of payloads by accelerator experiments has been a concern since their inception by Hess et al. (1971).
