Multichannel spark-gap technology for staged theta-pinch machines
Abstract
Triggered multichannel switches operating at voltages up to 180 kV with inductances of 10 to 15 nH were developed for the staged theta-pinch machines at LASL. These multichannel devices, depending upon their design, can switch up to 30 kJ per switch with peak currents up to 1 MA. The designs of the various spark-gap configurations are discussed from a mechanical and an electrical viewpoint. The switching modes including crowbar, high-voltage start, and high-voltage holdoff low-voltage start, as well as the experimentally determined triggering characteristics, are also discussed.
