AbstractLaboratory tests on charging and arcing of the solar arrays for satellites are carried out in a simulated geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) environment irradiating a solar array test coupon with an electron beam and gas plasma respectively in a vacuum chamber. In this study, the trigger arc inception on the solar array is examined at the inverted potential gradient. And, also examined is whether the interstring sustained arc occurs between adjacent cells of the array. In order to investigate sustained arc occurrence, applied were various potential differences with 0.55 A of line current in GEO environmental test, and applied were various potential differences, line current in LEO environmental test. The location of arc was observed by video images, and acquired were voltage and current waveform by several probes and data acquisition system. Secondary arc can be determined by those two methods. In GEO environmental test, secondary arc occurred frequently, especially under the severe condition. However, sustained arc did not occur, and other following conclusions were obtained. The possibility of being secondary arc and secondary arc duration also increases as the interstring voltage increases. In addition, it can be found that secondary arc duration increases proportional to the pressure increase. In LEO environmental test, the possibility of being secondary arc increases with interstring voltage. This result is well corresponding to the result of GEO environmental test. And, it can be confirmed that increasing line current may lead to an increase of secondary arc duration. In the case of changing line current, permanent sustained arc occurred at 3.0 A line current, in which case the interstring gap was 1 mm, and interstring voltage was 100 V. It was thought that this value may be used as the reference value of solar array design to avoid sustained arc.
