X rays from z-pinches on relativistic electron-beam generators

Abstract

This review summarizes recent experimental data on imploding z‐pinches and their radiation output, and gives an overview of theoretical issues concerning radiation production in the pinch plasma. A z‐pinch plasma is created when the current from a fast, powerful electrical generator compresses and heats a small amount of material between the electrodes. The hot, dense plasma emits copious amounts of radiation extending from the visible to the x‐ray region. With a 10‐TW electrical discharge the radiative power may be a few TW, with an energy per pulse of up to tens of kilojoules. Our interest is mainly in the photons with energy around 1 keV, which are useful in x‐ray lithography, microscopy, surface studies, and other applications.
