Scientific paper

We have been developing thermal detectors for X-ray astronomy. These detectors have the advantages of both high energy resolution and high quantum efficiency. A practical detector operating at a temperature of 0.1 K could ideally have a resolution as good as 1 eV (FWHM). We have produced a detector with a measured resolution of 7 eV (FWHM) for 6 keV X-rays. The detailed behavior of the detector thermistor and thermal links impose limits on performance. Techniques for improving detector behavior will be discussed. We are currently constructing an instrument for launch on a sounding rocket to observe the soft X-ray emission from the interstellar medium.
