13 December 2000 Imaging x-ray spectroscopy with superconducting phase transition thermometers
Author Affiliations +
We have developed cryogenic detectors based on superconducting phase transition thermometers (SPTs) for applications in x-ray astronomy. For a detector, which was designed for 1- dimensional imaging, an energy resolution of 216 eV (5.9 keV) and a position resolution of about 200 micrometer has been demonstrated over an absorber length as long as 1 cm. Finally, the possibilities for achieving better resolving power, improved position resolution, larger active area and increased counting capability will be discussed.
