摘要

摘要利用高速拍摄和阴影摄影技术，研究了氮气和氩气中 1.5 mm 长 "针（阴极）-平面 "间隙在 0.25 至 2 atm 压力范围内的脉冲放电空间结构。研究发现，在氮气中实现的是火花放电，而在氩气中实现的是弥散放电。对于这两种情况，在研究的压力范围内都发现了放电的微观结构，即放电是大量微米直径通道的聚集。研究表明，对于每种气体，在不同压力下放电辉光结构的动态都是相似的。已确定氮气中的放电辉光和微观结构与空气中的相似。

Dynamics of Structure of Pulsed Discharge in Nitrogen and Argon at Different Pressures in a “Pin to Plane” Gap

Abstract

Using high-speed shooting and shadow photography, the spatial structure of a pulsed discharge in a 1.5 mm long “pin(cathode)-plane” gap in nitrogen and argon in the pressure range from 0.25 to 2 atm was studied. It has been found that a spark discharge is realized in nitrogen and a diffuse form of discharge is realized in argon. For both cases, the presence of a microstructure of discharges in the studied pressure range was found, when the discharge is an aggregation of a large number of micron-diameter channels. It is shown that for each gas the dynamics of the discharge glow structure remains similar at different pressures. It has been established that the glow and microstructure of the discharge in nitrogen are similar to those in air.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
