Abstract

The experimental results of complex investigations of the high-current self-sustained glow discharge in helium at atmospheric lressure are presented. The studied discharge was produced in the current range 005 — 15 A. The electrical discharge power had been reached up to 3.5 kW. The different diagnostic methods are used: an electric probe, a tlurmopair, a laser, emission spectroscopy. The electric field strength, gas temperature, electron density and metastable helium atoms density are mapped. The obtained results are discussed with attraction of the existing theory of the cathode fall region taking into account the volumetric heat-evolution.
