N2 - The use of micron sized superconducting grains in the search for "dark matter" is discussed. Cosmions and massive neutrinos could produce count rates up to 106 per kg of active detector per day, and the signal could be differentiated from the background by the modulation produced by the Earth's motion around the Sun. We report a radiation test of a small superheated superconducting colloid in which 90 KeV γ-rays were detected using an rf SQUID. Individual "flips" of 5 μm radius grains were observed with a signal/noise ratio of 10.
