Transport of Electrons in NonThermal Noble Gas Plasmas (In German)
Abstract
For the transport of electrons in a nonthermal, weakly ionized plasma an analytical model and a detailed numerical calculation is presented. The following transport coefficients: mean energy, characteristic energy, mobility, diffusion coefficient, excitation and ionization coefficient for He, Ne, Ar, Kr, Xe are calculated in the region of reduced electric field 0.01 V/cm Torr ≦ Elp ≦ 100 V/cm Torr. The parameters of the model are developed using the existing experimental and our numerical data. With increasing E/p the dominant energy loss of the electrons changes from elastic to inelastic collisions and here from constant to increasing effective excitation energy. Three model regions of E/p result, in which the transport coefficients can be described as a power of E/p. The data presented here provide a starting point for further investigations of similarity rules and models of nonthermal plasmas.
