Abstract
- The anomaly of Japanese satellite ADEOS-2 (Advanced Earth Observing Satellite 2) appeared in 2003 is supposed to be caused by arcing discharge initiated due to ESD (Electrostatic Discharge) in the bundled wire-harnesses of the solar paddle. In order to make the conditions of the occurrence of the discharges clear, it is necessary to evaluate the discharge characteristics in vacuum quantitatively. Therefore we tried to investigate the characteristics of arcing discharge between two electrodes consisting of a pair of thin copper plates. The discharges were triggered by ESD released from a capacitor. These characteristics were obtained as parameters of the amplitude of the ESD, the pressure in the chamber and so on. We preliminarily obtained the result that the arcing discharge time increased with the amplitude of the ESD.<br />資料番号: AA0049206019<br />レポート番号: JAXA-SP-05-001E
