摘要：

The initial stage of micro-hollow cathode discharge was simulated with a self-consistent Monte Carlo model, formulated by modifying an ensemble Monte Carlo model by taking considerations of the weighted particles, distributions of electrons and ions, and Poison equation. Various variables, such as the spatial, energy and velocity distributions of electrons and ions, time evolution of electric fields were evaluated. The simulated results show that the superposed electric fields of the space-charges, anode and cathode have a major impact on the initial discharge at a high pressure. Driven by the potential difference between anode and cathode, the virtual anode, initially formed on the anode surface, propagates towards the hollow cathode, accompanied by formation of the cathode sheath of the hollow cathode. The virtual anode propagation model was found to describe well the initial discharge of micro-cathode at high pressure. ©, 2014, Science Press. All right reserved.
