Abstract
For various domains, from nuclear physics to cosmology, the low temperature methods present the advantage of possibly meeting two essential objectives: a massive amount of detecting material and a high energy sensitivity to particle stopping and induced processes. A large volume of a superconducting Vanadium absorber (V approximately 2 cm3), coupled to a superconducting Iridium transition edge thermometer has been used as a phonon detector at a temperature of Tb equals 120 mK. The phonon signals read out from the device were generated by the absorption of alpha-particles emitted from an Am/Cm/Pu nuclide source. Apart from the measured energy resolution of 95 KeV FWHM for a 5.48 MeV alpha- particle, the pulse height spectra exhibit events of lower energies. Subsequent investigations indicate that the low energy events originate from processes uncorrelated to the particle interaction.
