Description
Summary:The results of investigation of pulsed discharge in the trigger unit based on breakdown over the semiconductor surface in sealed-off cold-cathode thyratrons TDI1-50k/50 are presented. A method for estimation of surface discharge currents is proposed. Based on the 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 the semiconductor resistance delay times, the jitter also increases. The trigger circuit, which provides the jitter in delay times to breakdown in the thyratron main gap within 10 ns is proposed.
