Description
A laboratory experiment on the interaction between the high voltage solar array and the ambient plasma has been conducted.In the experiment, an array of electrodes distributed on the honeycomb structure CFRP panel was used to simulate the inter-connectors of the solar array. One of major concerns in the usage of the high voltage solar array in space is the arc discharge on the array. Based on the plasma sheath theories, there is a possibility to control or to prevent the discharge by selecting a potential distribution of the electrode array. As the first step to find the potential distribution which tolerates the discharge, we measured the distribution of space potential surrounding an array of electrodes and measured the current to the electrodes. This paper presents the preliminary results of the experiment suggesting that we can control the discharge by selecting a proper potential distribution of the high voltage solar array.
