Electrostatic discharges on a 1 sq m solar array coupon: Influence of the energy stored on coverglass on flashover current Amorim, Emmanuel Payan, Denis Reulet, Rene Sarrail, Daniel 静止軌道 ソーラーアレイクーポン 静電放電 地上試験 カバーガラス フラッシュオーバー電流 誘電体 航空宇宙環境 太陽電池アレイ 宇宙環境シミュレーション geostationary orbit solar array coupon electrostatic discharge ground test cover glass flashover current dielectric aerospace environment solar array space environment simulation Experiments simulating charging on a geostationary orbit were done in laboratory on a large solar array coupon (592 x 1,333 mm) in order to characterize electrostatic discharges. Such discharges were triggered by inverted voltage gradient situation produced on the coupon biased at - 5,000V by using an electron beam striking the sample. Current probes monitored blow-off and flashover currents produced by electrostatic discharges and showed that almost all the energy stored on the cover-glasses can participate to the flashover discharge. Surface potential measurements performed before and after electrostatic discharges, show neutralization area where the differential voltage between the cover glass surface and the coupon decreased from + 1,000 V to + 200 V. The size of the neutralization zone varied with the discharges: while some discharges produce neutralization on a limited surface, other can produce neutralization all over the coupon. 資料番号: AA0049206042 レポート番号: JAXA-SP-05-001E 宇宙航空研究開発機構 Japan Aerospace Exploration Agency (JAXA) 2005-08-01 eng conference paper https://jaxa.repo.nii.ac.jp/records/6357 1349-113X AA11984031 宇宙航空研究開発機構特別資料 JAXA Special Publication: 9th Spacecraft Charging Technology Conference JAXA-SP-05-001E 331 344 https://jaxa.repo.nii.ac.jp/record/6357/files/49206042.pdf application/pdf 6.4 MB 2020-01-16
