In this article we present the results of simulation of the initial discharge ignition in electronic equipment of spacecrafts which may appear inside spacecraft electronic equipment on the example of the external lacquer dielectric coating slot-hole defect between conductors. We solved the plasma physics task by COMSOL Multiphysics with a parametric sweep for each potentially vulnerable area in order...
The problem of breakdowns in equipment of spacecrafts operating on the Earth's orbit is based on multifactor physics involving vacuum electronics, plasma physics, and gas discharge physics. The problem was strongly escalated with increase of operating voltages from 27 V to 100 V followed by even higher voltages in the future. The problem is studied intensively in the course of last ten years, and...
A concept of a hybrid plasma source with a liquid gallium-indium propellant as a thruster for micro-satellites is proposed. Plasma source operates in two regimes: generating the laser ablation plasma and generating the plasma of low voltage vacuum arc discharge with a laser triggering. In the discharge cell of the source, the cathode is a stainless steel capillary tube filled with working liquid....
Summary form only given. The fast ionization wave (FIW) resulting from nanosecond pulsed discharge at very high overvoltage provides an excellent high reduced electric field (E/N) example discharge due to its spatial uniformity. A comprehensive model of FIW would provide insight into other high E/N discharges used for plasma ignition applications, such as DBD and streamer discharge. To that end the...
