Abstract

A microcalorimeter chip was fabricated by using 0.99SrTiO3-0.01SrTa2O6 dielectric material. After cooling down below 100 mK, the dielectric microcalorimeter was irradiated by α particles emitted from an 241Am source. The operating temperature of the dielectric microcalorimeter was maintained by operating a liquid helium-free compact dilution refrigerator. The dielectric microcalorimeter was irradiated by 5.5 MeV α particles emitted from an 241Am source at the temperature of 100 mK. By applying the bias voltage, detection signal pulses were observed at the output of a charge-sensitive preamplifier.
