Simulation of Electron Motion in a Micro-Hollow Cathode Discharge
Electron behaviors in the whole cathode space of a steady argon MHCD with a variable cathode gap have been simulated on the model of Monte Carlo collisions. As the cathode gap alters, the hollow-cathode effect in MHCDs has been studied by the variety rule of electron spacial and energy distribution. The results reveal that a too wide gap between two opposed cathodes under a settled pressure will die down the hollow-cathode effect.
