Description

technical field [0001] The invention belongs to the technical field of glow discharge, in particular to a device and method for generating glow discharge stripes. Background technique [0002] Glow discharge streak plasma is a low-temperature plasma under relatively harsh conditions. In addition to the basic characteristics of low-temperature plasma, its biggest feature is that the discharge stratification leads to the stratification of active particles. By developing this discharge layering technology and controlling the concentration of active particles in each layer, it can play a huge role in the application process. [0003] However, because it is usually difficult to achieve a uniform glow discharge under atmospheric pressure, filamentary discharge is very likely to occur in the axial direction, which affects the uniformity of the discharge, and even transitions to an arc discharge. There is an irregular distribution of electron density and electron temperature. There...
