Paper Abstract

A compact device, based on fast capillary discharge plasmas, is an intense EUV and soft x-ray source of radiation. Th plasma is created by a discharge of low-inductance capacitors through a gas-filled ceramic capillary. Parameters of the discharge are: maximum current of 25 kA at applied voltage 40 kV, a pulse duration of 20-30 ns at FWHM, and a rise time of 1.5 ns. The soft x-ray and EUV emission of multiply charged ions is investigated using a compact 1 meter grazing incidence spectrometer-monochromator with a constant angle of deviation. The use of various gases allows the observation of XUV spectra in a wide spectral range (4- 45 nm). A Xe-filled capillary discharge shows intense radiation near 13.5 nm - the region of interest for EUV lithography applications. A reflectometer is used for testing grazing incidence gratings.
