  • Glow discharge apparatus and a method of operating same
    Patent number: 4156828
    Abstract: A glow discharge apparatus consists of a discharge tube with an anode at end and a cathode at the other end. The anode has a flat surface facing the end of the discharge tube, and gas enters the tube via an annular gap formed between the flat anode surface and the end of the tube. The gas flowing in is thus directed initially radially over the anode surface and helps to cool at this surface. It is advantageous if the anode is able to move axially to alter the width of the annular gap. The gas can flow into the annular gap at the speed of sound.
