Abstract: The theory and experiment of a one‐dimensional low‐pressure discharge is presented. The discharge current is provided by a thermionic cathode that operates space‐charge limited. The primary electrons ionize the background gas and also heat the plasma electrons. The plasma characteristics (plasma density, electron temperature, and ion current density) and the discharge current are computed as functions of the discharge voltage and the neutral pressure. The model is self‐consistent and requires no experimentally determined parameters.

Conditions for the existence of a positively charged structure in a Penning discharge
TL;DR: In this paper, an analytical model for the high-current form of low-pressure glow discharge in a magnetic field is developed for the critical magnetic induction and critical pressure, below which it becomes impossible for this form of discharge to exist.

Generation of homogeneous plasma in a low-pressure glow discharge
S. P. Nikulin,S. V. Kuleshov +1 more
TL;DR: In this paper, the possibility of producing homogeneous plasma in a low-pressure discharge with the use of a hollow anode or hollow cathode was analyzed, and it was shown that nearly uniform radial distribution of the plasma parameters can be achieved under nonuniform ionization conditions by increasing the ionization probability at the system periphery and reducing it near the system axis.

Plasma Generation in a Non-Self-Sustaining Low-Pressure Discharge Supported by Electron Injection
TL;DR: In this paper, the conditions of plasma generation in a low-pressure gas discharge gap with injection of a flux of primary electrons are considered, and it is shown that the formation of a potential hump, considered in the classical Langmuir model, with maximum above the anode potential, is not obligatory.
The Influence of Primary Electrons on the Mechanism of Plasma Generation
S. P. Nikulin,S. P. Nikulin +1 more
TL;DR: In this article, it was shown that at high percentage content of primary electrons, plasma is generated due to the retention of ions in a potential well created by electrons and not due to accumulation of secondary electrons in the region of a potential hump formed by ions.
The current-voltage characteristic of a hot-cathode electric arc at low pressures
TL;DR: In this paper, it was shown that in a hot-cathode electric arc operating at low pressures of the working gas, a positive anode voltage drop arises that results in an increase in discharge voltage with current even before the transition of the discharge into a constrained arc.
