Features of the discharge formation in the trigger unit based on breakdown over the semiconductor surface in the sealed-off cold-cathode thyratron
The results of investigation of pulsed discharge in the trigger unit based on breakdown over the semiconductor surface in the sealed-off cold-cathode thyratrons TDI1-50k/50 are presented. Method for estimation of surface discharge current values is proposed. Based on data on current distribution between the trigger unit electrodes, the mechanisms of discharge formation in the trigger unit are revealed.Data on delay times and jitter in delay times to ignition of hollow-anode arc discharge in the trigger unit and to breakdown in the thyratron main gap were obtained. It is shown that with the increase of semiconductor resistance delay times and jitter increase. The trigger circuit, whichprovides jitter in delay times to breakdown in the thyratron main gap within 10 nsis offered.
