An ultra-compact back-lighted thyratron (BLT), which is also named as mini-BLT, with effective volume of 15 cm 3 was developed to serve as a high voltage switch in compact transient plasma ignition systems. The mini-BLT can hold off 40 kV and was used to conduct a peak current up to 4.5 kA. A 30 ns switching delay with 2 ns jitter was achieved when triggered by a 70 mJ, 355 nm laser pulse. Delay and jitter increase as the photon energy of the trigger pulse decreases. The plasma density in the switch measured at a peak current of 3.2 kA is 9×10 14 cm -3 . The mini-BLT was successfully used as the switch in a 100 ns, 60 kV pulse generator for generation of streamers in a plasma ignition system.

Dependence of pre-breakdown time on ionization processes in a pseudospark discharge AIP Advances 7, 115005 (2017); https://doi.org/10.1063/1.5003242Development of high-power gas discharge and electronic vacuum devices for pulsed electrophysic. This paper deals with the investigations of the sealed-off hold-cathode thyratron (pseudospark switch) TPI1-10k/50, which is commercially produced by the Pulsed Technology Ltd., Ryazan, Russia. The trigger unit of the switch is based on a low-current auxiliary glow discharge. The new method for the switch triggering is proposed. The essence of the method is that the thyratron grid and the hollow cathode of the auxiliary discharge has to be grounded and the trigger pulse is applied to the ring anode of the trigger unit. In the proposed method, an undesirable high-voltage spike at the thyratron grid, which can appear with a usage of the other methods of triggering, is absent. It is shown that to trigger the thyratron a critical pulsed current to the main cathode cavity at a level of 0.8 A and higher should be provided. When the current exceeds the critical value, the jitter in the delay time to triggering falls in a range of 10 ns. This means that the method of triggering can be used in a variety of applications that require a low jitter in the delay time. © 2017 Author(s).

Different electric circuits for triggering the switch with a trigger unit based on an auxiliary glow discharge are discussed. Most attention is concentrated on the recent experimental results on low voltage triggering of the switch and on the mechanisms for the main discharge initiation under the action of the trigger pulse. Due to modifications in the trigger electric circuit, the switch is triggered starting from a voltage of 50 V at a current level in the trigger circuit of 10 mA. With a voltage of 200-250 V and a trigger current of about 0.25 A, the delay time to triggering does not exceed 200 ns.Index Terms-Anode voltage drop region, cathode voltage drop region, hollow cathode pulsed discharge, pseudospark switch, steady state glow discharge.
