Low-energy X-ray detection in cryogenic detectors with tungsten thermometers

Technical Report:

Abstract

In the course of our development of calorimetric particle detectors with superconducting phase transition thermometers, we have succeeded in depositing epitaxial {alpha}-tungsten films on sapphire which have critical temperatures T{sub c} near 15 mK. To our knowledge this is the first time that the T{sub c} of bulk tungsten has been observed in thin films. Such films used as thermometers are very sensitive and provide good energy resolution: with 4 g and 32 g sapphire crystals energy resolutions of better than 100eV (FWHM) for 1.5 KeV X-rays have been achieved.
