Abstract
We designed and fabricated a hard X-ray and gamma-ray TES spectrometer for nuclear materials analysis. The superconducting tin absorber is coupled to an Ir/Au TES by using a gold post to improve the thermal contact between the absorber and the TES. The reported energy resolution is 156 eV FWHM at 59.5 keV and 166 eV FWHM at 122 keV gamma-rays. We performed measurement of a Pu sample and clearly separated the \(^{239}\)Pu (56.828 keV) and the \(^{241}\)Am (59.5 keV) peaks by this TES microcalorimeter which cannot be resolved by the HPGe detector.
