A prototype dielectric microcalorimeter was fabricated from 0.99SrTiO 3-0.01SrTa2O6, a dielectric material. To estimate the operation performance of the microcalorimeter, a simple evaluation model is introduced by employing the block diagram formalism. Pulse height and fall time constant of the detection signal are analyzed as a function of the thermal conductance of the heat link. The dielectric microcalorimeter maintained at 100 mK was irradiated by 5.5 MeV α-particles emitting from an 241Am source. Responsivity was found to be 2.7×10 -19C/eV.
