Abstract
The turn-on delay of a cold cathode gas tube, such as a gas laser, is significantly reduced by the inclusion of an electric field concentrator in a region of the tube between the tube anode and cathode. The concentrator can take the form of a projecting conductive member having a sharp corner, linear or curved knife edge, needle like points, or combinations of such geometries.
