Abstract: A gas-discharge tube capable of sustaining a cold-cathode arc enables the switching of high-current pulses with a duration of one microsecond at a rate in excess of 100 KH. The operative surface of the cathode bounds at least one cavity in the cathode such that for a majority of points on the surface the outward normal to the surface intersects the surface at a distance not exceeding 5 millimeters and preferably not exceeding 2 millimeters. The cathode surface may be the surface of an annular slit and the cathode material may be copper.
