A nonlocal model of spatially nonuniform positive column of DC discharge
Annotation
A self-consistent kinetic model is given of the positive column of low-pressure low-current dc discharge in neon in a tube of circular cross section, which is nonuniform in both the radial and longitudinal directions. The model is based on the solution of kinetic equation for the electron distribution function in nonlocal approximation, of drift equation for ions, of diffusion equation for metastable ions, and of Poisson equation for electric field. Calculations are performed for the case where the longitudinal nonuniformity of discharge is caused by a jumpwise variation of the discharge tube radius.
