Abstract
We report on the first experiments with a composite magnetic bolometer whose mass is 7.5 grams. The thermal pulses produced by single 5.5 MeV α-particles have been measured with a SQUID yielding a pulse height of 165 mV at a noise level of 2 mV. Thus, the energy resolution is 65 keV and the resolution related to the mass of the detector ΔE/m is 8.7 keV/g. This last number is three orders of magnitude better than with other bolometers. Further developments for detecting neutrinos are pointed out.Keywords
