“…The generation of high-voltage fast pulses usually needs multi-stage compression and superposition of primary pulses [1][2][3], which requires high-voltage pulsed switches with low jitter. Working mechanisms of externally triggered switches such as laser-triggered switches [4][5][6], trigatrons [7][8][9] and V/n switches [10] are relatively clear, and their jitter can be less than 1 ns [11][12][13][14]. The operating voltage of a laser-triggered switch can exceed 6 MV [4].…”

This work investigates the pulsed breakdown processes and mechanisms of self-triggered pre-ionized switches with a four-electrode structure in nitrogen through ICCD (Intensified Charge Coupled Device) photographs. The diameter of the trigger plane hole mainly determines the switch’s electric field distribution. Two configurations with minimum and maximum trigger plane holes are adopted for comparison. In the switch with a minimum trigger plane hole, the maximum electric field distributes at the surfaces of the main electrodes. Though charged particles in the triggering spark channel cannot drift out, homogeneous discharges can be stimulated from both the cathode and anode surfaces through UV (ultraviolet) illumination. Two sub-gaps are likely to break down simultaneously. In the switch with a maximum trigger plane hole, the maximum electric field locates near the trigger electrodes. Discharges in both sub-gaps initiate from the trigger electrodes in the form of a positive or negative streamer. Due to lower breakdown voltage and electric field threshold for discharge initiation, the cathode side sub-gap breaks down first. The analysis of two extreme examples can be referenced in the future design and improvement of self-triggered four-electrode switches with different structures of trigger electrodes.

“…Electrode erosion is the important factor that results in reduction of the switch self-breakdown voltage and increase in triggering jitter, directly impacting the service performance and reliability of the switch and reducing the service life of the switch [1][2][3][4][5]. Therefore, electrode erosion is a key restrictive factor in high-power gas switch development and application [6][7][8][9].…”

Gas switch is one of the key elements in pulsed-power devices, and electrode erosion is a key restrictive factor in high-power gas switch development and application. According to the thermal equilibrium equation near the electrode surface, this paper calculates electrode heat fluxes and their peak powers caused under different discharge conditions, and analyses their effects on the removal method of electrode materials. When discharge current is not too high, calculation results indicate that the arc joule heat is the main cause of electrode erosion and solid material removal may appear. Vaporization of electrode material is the main cause of electrode erosion when discharge current is high enough.
