Abstract
A unique feature of high-current vacuum spark discharges is the occurr ence of one or a few extremely hot and dense micropinches, which are i ntense emitters of radiation in the x-ray region. We report on investi gations of such hot plasma points of Al, Fe and Mo and on a comparison of their parameters with predictions by a radiative collapse model. T he agreement is good. The origin of the K(alpha)-radiation in the case of high atomic number elements is discussed, and the potential as a s ubnano-second high-brightness x-ray source is pointed out.
