Abstract
We have developed a Penning discharge lamp for use in the calibration of instruments and components for the extreme ultraviolet. This source is sufficiently light and compact to make it suitable for mounting on the movable slit assembly of a grazing incidence Rowland circle monochromator. Because this is a continuous discharge source, it is suitable for use with photon counting detectors. Line radiation is provided both by the gas and by atoms sputtered off the interchangeable metal cathodes. Usable lines are produced by species as highly ionized as Ne IV and Al V. The wavelength coverage provided is such that a good density of emission lines is available down to wavelengths as short as 100Å. This source fills the gap between 100 and 300Å which is inadequately covered by the other available compact continuous radiation sources.
