Abstract
In a glow discharge supported by a hollow cathode and a mesh anode, three-dimensional distributions of the parameters of the electronic component of the plasma were obtained for the first time by the Langmuir probe method both in the discharge volume and in the post-anode plasma. It has been experimentally established that the anode glow formed under discharge conditions in this work completely surrounds the anode. A mechanism for plasma formation behind the anode is proposed, when most of the electrons fly around the anode, thus there are curved trajectories of electron movement in the discharge, which ensure their entry into the anode from the opposite side to the cathode.
