Abstract

It was attempted to use the vacuum arc discharge as a load of a high-current generator. The idea is as follows: metal vapor is injected using the vacuum arc discharge into a microgap of a load unit of the current generator. When the generator current flows over metal vapor, such a load begins to compress as in the classical Z pinch. During compression, Rayleigh-Taylor instabilities develop, which results in the formation of waists and hot spots. The hot spot radiation power can exceed the radiation power in the case of the X pinch used as a load by a factor of 1.5-2. The signal amplitude spread is significantly smaller than that when using the X pinch. The spectrum and sizes of the hot spot can be varied by selecting the mass and type of metal injected into the discharge region.
