Abstract :
Presented are the results obtained in recent Magnetically Controlled Plasma Opening Switch experiments in submicrosecond conduction time range on the terawatt GIT-4 pulser at Institute of High Current Electronics. The opening time control was provided by variation of both slow magnetic field and fast magnetic field amplitudes in switch region. The additional trigger Plasma Opening Switch placed in fast coil circuit allowed to vary the fast coil “turn-on” and risetime of fast magnetic field. We investigated switch performance for both plasma injection directions: along slow magnetic field lines and across them. The coaxial inductance or electron beam diode served for a load in the experiments. The switching characteristics were studied as functions of plasma parameters.
