Abstract

PURPOSE:To improve stability and reliability of discharge by installing an element for generating magnetic field such as a permanent magnet near the surface of anode electrode to configure so that magnetic field is applied vertically near the outer surface of cathode electrode and in coaxial direction in reference to the electric field which is applied between anode and cathode electrode. CONSTITUTION:When discharge tries to move from a position (a) to an outer periphery of electrode (b) and then further to the outside, force is applied so that it may rotate around the periphery of cathode electrodes 3 and 4 due to the influence of a magnetic field B and is enclosed within the cathode electrodes 3 and 4. Thus, there is no output reduction due to move of discharge to an electrode support part 8 and hence the discharge becomes stable. Also, since electric field (discharge) is applied in coaxial direction, an effect for reducing discharge start voltage is applied, thus realizing a gas laser tube with a stable discharge, long life, and improved reliability. Elements for generating magnetic field 9 and 10 can create the same effect for both permanent magnet and electromagnet.
