ABSTRACT:
In addition to the anode and cathode electrodes which define a low pressure gas filled main gap therebetween and a magnetic field to lengthen the electron path, the crossed-field switch device has a control electrode defining a second gas filled control gap in communication with the first, main conducting gap. An auxiliary voltage supply can be connected to the control gap to ignite a low pressure discharge, and the ionized plasma of this discharge leaks into the first gap to start a discharge in the glow mode.
