INFLUENCE OF THE MAGNETIC FIELD OF THE CURRENT PASSING THROUGH THE ANODE ON A GLOW DISCHARGE IN A COAXIAL SYSTEM

To study the influence of the magnetic field on the normal low-pressure glow discharge, an electrode coaxial system with a meshy tubular cathode and an internal anode was used. A current was passed through the anode to obtain the azimuthal magnetic field crossed with electric field. Oscillography of the signals from the electric probe and photodiode, together with video recording, made it possible to establish the movement of the discharge luminous region along the electrodes. When AC current with a frequency of 50 Hz was passed through the anode, the discharge movement was oscillatory – from one end of the system to another.
