Diagnostics of primary arcing in electronics of satellite telecommunication systems

In this paper we propose a modern theoretical approach for complex diagnostics of onboard electronic equipment for the occurrence of primary electric arcing in satellite telecommunication systems. Our method based on the gradual partitioning of the electronic device into regions potentially vulnerable to primary arcing. We solve complete plasma physics problem with parametric sweep for each vulnerable region as an independent computational plasma physics problem in order to obtain the critical parameters diagram. It shows most dangerous and least dangerous ranges of critical parameters with respect to the possibility of arcing in spacecraft operating conditions. A large set of two- and three-dimensional critical parameters diagram is widely used for complex diagnostics and development of arc-resistant electronic systems.
