The Hybrid X-Pinch as a Source of XUV Radiation

The first detailed study of hybrid X-pinch (HXP) radiation in the wavelength range 10-200 Å on the BIN pulser (270 kA, 100 ns rise time) is presented. X-pinch loads were made from Al, Mo, Ag, and W wires with 13-30 μm diameters. Time-integrated images were obtained using open pinholes with 100 μm aperture. Spatially resolved XUV spectra were recorded using a transmission grating spectrograph on UF-4 film and with Fuji TR image plates. Signals from calibrated photoconducting detectors enabled estimates of the absolute yield of radiation and showed that Mo HXPs radiate about 100× more energy in UV radiation than in X-rays with energy above 1 keV.
