Transformation of the Electron Energy Distribution Function near a Rectangular Hollow Cathode

Using the improved method of single Langmuir probes, the electron energy distribution functions (EEDF) are 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 el...

Zusammenfassung:Using the improved method of single Langmuir probes, the electron energy distribution functions (EEDF) are 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.
