研究了环境等离子体对负偏置太阳能电池阵列电弧特性的影响。检测的电弧特性是电弧期间的峰值电流，电弧终止时的衰减时间，以及电弧期间的电荷损失。这些电弧特性在氮气等离子体中进行了测试，其电荷密度为15,000至45,000 cucm，背景气体压力为8 × 1,000,000至6 × 100,000 torr。在这些参数范围内，对电弧特性没有明显的影响。研究了氦、氮、氩三种气体的电弧特性。氦弧比氮弧和氩弧具有更高的峰值电流和更短的衰减时间。氮气和氩气的电弧特性稍有不同。这些差异可能是由各自物种的质量差异引起的。此外，证据提出了一个电子发射机制出现作为太阳能阵列电弧的前兆。等离子发生器偶尔会被关闭，但在真空系统中仍能检测到电流。当这些电流出现时，就可能产生电弧。
The influence from the ambient plasma on the arc characteristics of a negatively biased solar cell array was investigated. The arc characteristics examined were the peak current during an arc, the decay time as the arc terminates, and the charge lost during the arc. These arc characteristics were examined in a nitrogen plasma with charge densities ranging from 15,000 to 45,000 cu cm. Background gas pressures ranged from 8x1,000,000 to 6x100,000 torr. Over these ranges of parameters no significant effect on the arc characteristics were seen. Arc characteristics were also examined for three gas species: helium, nitrogen and argon. The helium arcs have higher peak currents and shorter decay times than nitrogen and argon arcs. There are slight differences in the arc characteristics between nitrogen and argon. These differences may be caused by the differences in mass of the respective species. Also, evidence is presented for an electron emission mechanism appearing as a precursor to solar array arcs. Occassionally the plasma generator could be turned off, and currents could still be detected in the vacuum system. When these currents are presented, arcs may occur.
