Transformation of the Electron Energy Distribution Function Near a Rectangular Hollow Cathode
https://doi.org/10.56304/S207956292201002X
Abstract
Using the improved method of single Langmuir probes, the electron energy distribution functions (EEDF) were obtained in a short (10 mm) discharge gap between a rectangular hollow cathode and a mesh anode. It was found that the electron distributions are not Maxwellian with an excess of high-energy electrons (10–20 eV), the proportion of which decreases with distance from the cathode. The features are associated with the nonlocal mechanism of the EEDF formation.
