Abstract

To improve the sensitivity of calorimetric particle detectors we want to produce low-Tc superconducting thin films to be used as phase transition thermometers. We have succeeded in depositing epitaxial α-tungsten films on sapphire which have critical temperatures Tc near 15 mK. To our knowledge this is the first time that the Tc of bulk tungsten has been observed in thin films. Such a film has been produced on a 4 g sapphire crystal and operated as a calorimeter, giving an energy resolution of 75 eV (FWHM) for 1.5 keV X-rays.
