Low Temperature Microcalorimeters for Decay Energy Spectroscopy

Low Temperature Detectors have been used to measure embedded radioisotopes in a measurement mode known as Decay Energy Spectroscopy (DES) since 1992. DES microcalorimeter measurements for applications ranging from neutrino mass metrology safeguards and medical nuclides. While the low temperature detectors extremely high intrinsic energy resolution (several times better than semiconductor detectors), achieved practice is strongly dependent on factors such sample preparation method. This review seeks present literature consensus what has learned by looking at function of various choices detector, absorber, methods.
