“…This indicates that the single-channeling trigger gap must be the focus to improving switching performance for both inductance and resistance. Hybrid trigger schemes have been utilized to address the large inductance of a single-channeling gap, but the designs tested to date have provided no conclusive solution [3].…”

Many pulsed power applications require multichannel switching because of stringent low erosion and low impedance requirements. Rimfire, which is a multigap multichanneling switch, has been implemented extensively for this purpose at Sandia National Laboratories for several decades, but with incomplete understanding. This paper presents a thorough experimental analysis of impedance and multichanneling characteristics for a multigap switch under the influence of a laser trigger and in an SF 6 environment. The implications of these results on the future design of multichanneling multigap gas switches are also presented.Index Terms-Gas switch impedance, laser-triggered gas switch, multichannel gas switching, pulsed power system switches, rimfire.

“…The LTGS was tested in the Advanced Pulsed Power Research Module (APPRM). APPRM was originally constructed as a test bed for the development of pulsed power technologies and components that could be used in future generation high power facilities [8]. The test bed is comprised of a 56 stage, 2.2F 100 kV Marx generator that charges a 5.5 Ω 20 nF water insulated Intermediate Storage Capacitor (ISC) to more than 7 MV in ~1.5 s [8].…”

Ultraviolet (UV) illumination can effectively shorten the statistical lag and jitter in gas breakdown processes. The spark gap discharge can produce abundant spectrum including UV waveband. In this paper, a simple but reliable spark gap operating with N 2 at atmospheric pressure is used to test optical radiation characteristics, such as spectrum intensity, rise time, fall time, and duration of optical pulse, which are adjusted by changing the circuit or configuration parameters. Three UV-illuminated switches with different UV spark gap configurations have been tested. The experimental results approve our assumption. With a uniform electric field UV spark gap, the breakdown voltage standard deviation percentage of the switch is 0.74%.Index Terms-Breakdown characteristics, jitter, optical pulse parameter, pulsed power technology, pulsed switch, ultraviolet (UV) illumination.
