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. T

We measured the temperature dependence of the emission wavelength spectrum of YAP:Yb by irradiating with β - rays from a 90 Sr/ 90 Y source in the temperature range from 4.2 to 175 K. The light yield of YAP:Yb was characterized using an avalanche ph

We measured emission wavelength spectra, scintillation decay time and scintillation light yield of 6LiI(Eu) in the temperature range from 4.2 K to 300 K. We observed that the scintillation decay time was almost constant (1.3 μs) below 100 K. At 4.2

A transition edge sensor (TES) microcalorimeter has been developed for use as an energy dispersive X-ray spectrometer. The TES microcalorimeter is a thermal detector that enables one to determine the energy of an incident photon by measuring the resu

A Li-glass scintillator was placed in the slow neutrono eld at temperatures of 300 K and 77 K. An avalanche photodiode (APD) was employed for converting scintillation photons into voltage signal pulses. A peak corresponding to the Q-value of the 6 Li
