Experimental verification of the technique for calculating a plasma opening switch and its matching to the load

A technique for calculating a plasma opening switch in an external magnetic field and its matching to a load the impedance of which increases with time was verified experimentally. The experiments were performed in the RS-20 facility both in the absence of a load and with various inductive loads. The amplitude of the voltage pulse at the input of the plasma opening switch was 0.36-0.84 MV, the current amplitude was 280-320 kA, and the pulse duration was ∼2 μs, whereas the corresponding parameters of the output pulse were 0.8-3.2 MV, 0-240 kA, and ∼100 ns.
