Abstract: A conducting crossed-field switching device in a high voltage circuit can be offswitched by temporarily reducing the magnetic field to non-conductive conditions. While high voltage rises across the offswitching crossed-field device, the magnetic field strength-reducing pulse dissipates, but the conditions in the interelectrode space remain non-conductive.

Abstract: The switching device has an anode and a cathode with a gasfilled annular space therebetween. When an axial magnetic field above a critical value is applied to the gas-filled space, and after initation, cascading ionization occurs for conduction. The magnetic field above the critical value is supplied by a substantially fixed field source, and reduction below the critical value is accomplished by employing one of the electrodes as a coil through which current can be passed to change the total magnetic field with respect to the critical value.

Abstract: The switching device has three spaced electrodes with a gasfilled annular space therebetween. When an axial magnetic field above a certain value is applied to the gas-filled space, and after initiation, cascading ionization occurs for conduction. The electrodes can be electrically serially connected for higher holdoff voltage during nonconduction, or can be electrically connected in parallel for higher current capacity in the same envelope.

Abstract: The switching device has an anode and a cathode with a gasfilled space therebetween. Conduction causes ion implantation into the cathode, sputtering and adsorption pumping, with consequent reduction in gas pressure to result in cessation of conduction when the pressure decreases below the critical value. In the present switching device, this is prevented by providing an auxiliary gas volume which contributes gas as required.
