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 \mu \text{m} diameters. Time-integrated images were obtained using open pinholes with 100~\mu \text{m} 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\times more energy in UV radiation than in X-rays with energy above 1 keV.
