Methods of triggering for the cold cathode thyratrons with auxiliary glow discharge in trigger system

The paper describes the schematic design and principle of operation for the ceramic-metal sealed-off pseudospark switches with the auxiliary glow discharge in the trigger unit. The switches are produced commercially by the Pulsed Technology Ltd., Ryazan, Russia [http://www.pulsetech.ru/index.htm] and are known as the switches of TPI-series whose anode voltage ranges from several to 50 k V. Proceeding from the switch design and the methods of triggering, the TPI switches can be referred to as the cold cathode thyratrons. Triggering methods for the electric circuits corresponding to grounded grid thyratron and to classical thyratron with cold cathode are considered.
