Cryogenic detectors based on iridium–gold phase transition thermometers are being developed for various applications in astroparticle physics, aiming at high energy resolution, low energy threshold and moderate count rates. A microcalorimeter with an energy resolution of 15.5 eV (FWHM) for the 55Mn Kα1 x‐ray line for tentative use in an analytical x‐ray system (e.g. SEM, TRFA) is presented.
