Abstract—
In the region of the surface of the probe introduced into the plasma, there are emission flows that introduce changes in the determination of its parameters. Despite the significant development of the theory of probes, when calculating plasma parameters for experimentally obtained current–voltage characteristics, electron emission is not taken into account, largely due to the serious complication of the mathematical apparatus. The authors calculated the probability of electron emission from a rough surface without collisions. Characteristics of probes from various materials (nickel, wolfram, molybdenum) in a glow discharge in helium are presented. The analysis of the chemical composition of the probe materials is carried out. It has been experimentally shown that the material of the probes and the state of their surface (degree of roughness) affect the results of probe measurements.中文翻译:
