“…These models can explain some phenomena taking place in gas discharge but can't describe the concrete details of it. With the development of modern computer and computing technology, some new theories and models about gas discharge have been developed in recent years in which fluid model [4] and particle in cell (PIC) model [5] are typical representatives. These two models are based on Boltzmann equation and the effect of space charge which is important in gas discharge can be acquired.…”

There are great differences between vacuum discharge and common gas discharge. For short gap gas breakdown, the main reason can be explained as followings: electrons from the cathode emission are accelerated by the electric field and impact the anode which will release a lot of metal vapor. The ions produced by the collisions between metal vapor gas molecule and electron impact the cathode and secondary electrons emission will come into being. Based on the field emission theory in vacuum, particle in cell simulation method is used in our paper to trace the motion of electrons produced by cathode emission and ion produced by collision in time and space dimensions. Mont Carlo method is used here to cope with the collisions between electrons and neutral molecules. The cross sections of the collision which relate with the energy are all from the experiments. The secondary electron emission, exciting, elastic and ionizing collisions between electrons and metallic vapor molecules have been considered in our paper. The state parameters of charged particles at any position and time are recorded and the effect of vacuum degree on discharge voltage are simulated which can explain the mechanism of vacuum discharge from microscopic view.I.

Paschen curves and current–voltage characteristics of large-area short glow discharge with different electrode structures

et al. 2020

View full text Add to dashboard Cite

In this work, the Paschen curves and current–voltage characteristics of three large-area short glow discharge structures with grid and solid plate electrodes are studied. The study of the Paschen's curves reveals that Paschen's law is broken for all three investigated electrode structures. It is shown that the experimentally measured Paschen curves are well approximated with a modified Paschen's law. A comparison of the current–voltage characteristics of the short glow discharge in the three types of electrode structures reveals that the use of grid electrodes allows for the increase in the discharge current. The effects of the electrode gap, which were varied from 1 mm to 7 mm, on the Paschen curves and current–voltage characteristics of short glow discharges are also investigated.
