“…Energy can be stored in an inductor at low voltage, relaxing insulator design requirements and extracted on a shorter time scale at a higher power level. Present opening switch technology involves the use of explosively activated circuit breakers, 2 wire fuses,'' 3 ' 4 electron-beam (e-beam) controlled diffuse discharges, 5 and various injected plasma schemes. 6 In this paper we report experiments with a new type of opening switch which operates on a nanosecond timescale.…”

The first results of experiments using plasma opening switches for inductive energy storage are described. The switch has been shown to conduct up to 200-kA current for ∼50 ns then to open in <10 ns, transferring the current to an electron beam load. Inductive energy storage, pulse compression, and power multiplication are demonstrated. A simple model explaining the switch operation is presented.

A gas discharge is simulated and numerically studied in the gaseous helium in the region of the squeezed state of a single tubular magnetized relativistic electron beam at its partial reflection from a magnetic mirror. The code based on the particle-in-cell/Monte Carlo method was used. The electron beam dynamics, time evolution of phase portraits of particles, physical parameters, and spatial-time characteristics of plasma were calculated. It is shown that dense plasma appears in the cavity under the action of an electron beam in the form of a thin-walled long cylinder of a large length; its electron concentration can be several units of 10 11 cm −3 . At the same time, it turned out that plasma is considerably inhomogeneous in length; its more dense part corresponds to the part of the squeezed state of a beam. The time dependence of the charge compensation of electrons on the helium atom concentration in the chamber was calculated. The dependence turned out to be decreasing since the rate of discharge development is increasing with the growth of the helium pressure in the cavity.

“…Other discharge properties and mechanisms of importance in the discharge have to be considered and their collective influence on the coupling between discharge and circuit must be optimized in a different way. 0263-0346/84/0000-0000$05.00 G. Schaefer et al Recently several papers (Fernsler et al 1980;Commisso et al 1982;Commisso et al 1983;Bletzinger 1981;Hallada et al 1982;Bletzinger 1983;Kline 1982;Dzimianski & Kline 1980;Lowry et al 1983;Schoenbach et al 1982;Harjes et al 1983;Schaefer et al 1983) have appeared concerning e-beam controlled discharges. They specifically relate to switching applications, emphasizing different aspects of modes of operation, such as the influence of the gas mixture (Fernsler et al 1980;Commisso et al 1982), the cathode sheath (Hallada et al 1982;Bletzinger 1983), the low e-beam current density and high current gain regime (Kline 1982;Dzimianski & Kline 1980;Lowry et al 1983), as well as related optical control mechanisms Schaefer et al 1983).…”

“…The use of admixtures of attachers can be employed to achieve fast opening of the switch but attachment will also increase the losses (Fernsler et al 1980;Commisso et al 1982;Bletzinger 1981). It has been proposed that these switch losses can still be kept low, if the gas mixture has the following properties, allowing both low forward voltage drop and fast opening (Kristiansen & Schoenbach 1981;1982): a) at low values of E/N, i.e.…”

The use of attachers in electron-beam sustained discharge switches—theoretical considerations

et al. 1984

Electron-beam sustained discharges can be used in opening and closing switch applications for producing bursts of energy in pulsed power systems. The incorporation of admixtures of attachers with low attachment rate at low values of E/N and high attachment rate at high values of E/N in the gaseous switch dielectric has been proposed to achieve low forward voltage drop in the conduction phase as well as rapid opening when the sustaining e-beam is terminated. This paper presents model calculations on the characteristics and transient behavior of an electron-beam sustained discharge in the high current density regime in N 2 . The influence of an attacher (N 2 O), with the property described above, and of the circuit parameters on the discharge is investigated as an illustrative example. The advantage of using such an attacher is demonstrated for the steady state conduction phases and for the opening phase, while the closing process is obstructed by the attacher. Additional possible control mechanisms, such as photodetachment to aid the closing process are discussed.
