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.

探针表面的材料和粗糙度对探针特性的影响

摘要-

在引入等离子体的探针表面区域中，存在发射流，这些发射流会改变其参数的确定。尽管探针理论有了长足的发展，但在计算通过实验获得的电流-电压特性的等离子体参数时，并未考虑电子发射，这主要是由于数学仪器的严重复杂性。作者计算了从粗糙表面发射出无碰撞电子的可能性。介绍了氦气辉光放电中各种材料（镍，钨，钼）探针的特性。进行探针材料的化学组成分析。
