Experiments with the Tiny Nanosecond Output Device on the S-300 High-Current Generator (original) (raw)

Abstract

On the S-300 pulsed power generator (4.5 MA, 70 ns, 0.15 Ohm), within the frames of ICF program based on fast high-current Z-pinches, experiments are being carried out studying promising schemes of output units. In par-ticular, a device similar to the plasma flow switch is being investigated aimed at sharpening the pulse. In the ex-periments with such a device, by means of variation the geometry of the inner electrode of a co-axial, as well as the acceleration of a cascade of plasma "washers", the switching of the current up to 750 kA has been obtained, with the rise time ~ 5…7 ns and subsequent decrease being in accordance with that of the net current (~ 100 ns). Thereby the opportunity of switching of much more amount of energy onto the load has been demonstrated compared to our pre-liminary experiments (2.5 MA/2.5 ns). Soft X-ray radiation from the cavity was recorded by means of vacuum di-odes with a nickel cathode and especially selected filters. The radiative tempera...
