Abstract

A simple XUV transmission grating spectrography operating in the wavelength range of 3-90 angstrom with sub-angstrom resolution without using any XUV imaging optics is described. This is based on a free-standing gold microstructure grating of 2000 angstrom period in normal incidence geometry. A spectral resolution of 0.6 angstrom is obtained by optimizing the slit aperture, the source to grating and the grating to detector distances. Electron temperature deduced form analysis of the spectrum of a laser produced magnesium plasma using a plasma spectroscopic code are consistent with theoretical considerations.
