Abstract

The x-ray microcalorimeter represents a revolutionary development in x-ray astronomy, because it permits spectra to be obtained which rival Bragg crystal spectra in resolution, and exceed a proportional counter in efficiency. We describe a rocket borne x-ray spectrograph, consisting of a microcalorimeter detector array placed at the focus of a Wolter I collector. We demonstrate that a modest collecting area of 60 cm² is sufficient to determine the abundances of O, Ne and Fe in the interstellar medium.
