High Resolution Alpha Particle Spectroscopy with Cryogenic Microcalorimeters

We present measurements from a novel cryogenic microcalorimeter designed to detect alpha particles. We demonstrate a spectral resolution of 4.4 keV FWHM for 5.3 MeV alpha particles from a 210 Po source. In addition, we present an alpha spectrum from a mixture of Pu isotopes demonstrating the feasibi...
