Abstract : A study of the extreme ultraviolet radiation emitted by ion beams of highly ionized neon and argon after passage through thin foils was conducted at the variable energy cyclotron at Texas A&M University. A grazing incidence spectrometer was equipped with a position sensitive microchannel plate (MCP) detector which improved the detection efficiency by two orders of magnitude. The position information of the MCP was determined to be linear over 90% of the 50-mm-wide detector. Spectra spanning regions of over 100 angstroms were accumulated at a resolution of less than 1 angstroms. A wavelength calibration based on a second-order equation of spectrometer position was found to result in an accuracy of + 0.1 angstroms.
