“…In a large diameter shunt for use with high currents it was necessary to support the shunt foil on a suitable backing, usually a thin layer of insulation with a massive metal supporting cylinder behind as described by Thornton (1960). This configuration, shown diagrammatically in figure 4, differed from figure 1(b) in that the shunt foil was no longer part of the coaxial conductor wall, but formed a separate section outside it.…”

“…However, experience with currents of several hundred kiloamps for times of less than 10 ps has shown that thin metal-foil shunts of diameters greater than 150 mm have adequate mechanical strength when suitably confined within a cylindrical block of epoxy resin. A shunt made in this way was described by Thornton (1960) and it was found that the combined mechanical inertia of the thin foil and the confining epoxy resin was adequate to prevent damage. 2 Calculation of shunt risetime The performance of a cylindrical shunt to a suddenly impressed current waveform of sinusoidal shape was analysed by Bennett and Marvin (1962).…”

The design of a metal-foil current shunt for the absolute measurement of currents of the order of 100 kA and 100 ns duration is considered. When the metal foil is thick (> 100pm) the risetime of the shunt is determined by the time of diffusion of current through the foil in agreement with the calculated value, but as the foil thickness is reduced, pulse transit-time effects are observed to limit the risetime to the order of 5 ns. Optimization of the shunt configuration to give the best time response and to meet the requirements of high voltage output and high current operation in a specific application is discussed.

Instrum. 49, 1537 (1978); 10.1063/1.1135307 A simple, fast−closing, metallic contact switch for high voltage and current Rev.A metallic contact solid dielectric switch with a closing time of 1O.13±0.31I'sec is described. An electrically exploded foil is used to drive a 0.317 cm thick aluminum plate through 0.076 cm polyethylene insulation into solid contact with the other switch electrode. The switch has been used asa series switch in a 20kV circuit with a current of 1.2Xl()6 A rising in 401'5ec. In a "crowbar" application it has carried 40 kA with a l/e decay time of 45 msec.
