Abstract The dynamics of the main characteristics of a limited nanosecond discharge in an extended slot cathode in argon at the values of the applied voltage to the electrodes close to the values of the voltages of the formation of a volume discharge are studied by numerical simulation. It is shown that this type of discharge can be used to create an extended dense plasma column with a high density of charged and excited particles. The analysis of the spatiotemporal dynamics of development of the electron density and the electron energy distribution function was carried out. It is shown that the high-energy electrons are formed at the front of the ionization wave due to the hollow-cathode effect.

This paper presents results of measurements of the electron energy distribution function (EEDF) in the range 0 - 40 eV, and the electron density and the space potential for the helium plasma of a longitudinal discharge in a hollow cathode as used for He-inert gas and He-metal vapour lasers. The results show that the EEDF and also the mean electron energy, the electron density and the plasma potential differ from those typical of the transverse hollow-cathode discharge.
