Abstract
The effect of a longitudinal magnetic field on the electrical and optical properties of negative glow and the Faraday dark space of a glow discharge in helium is experimentally studied at a discharge current J d=11 mA and a pressure of 100–150 Pa in the discharge chamber. An experimental setup is designed and described. A longitudinal electric field is found to be absent in the region of negative glow and the Faraday dark space in both the presence and the absence of the magnetic field. The magnetic field is shown to decrease the voltage of the glow discharge and to increase the total discharge luminosity and the intensities of some spectral lines by a factor of 10–12. The experimental results are explained.
