Abstract :
We report two tests designed to study the practicality of a superheated superconducting colloid detector using a SQUID read-out system. In the first test, the individual ´flips´ of ten 15 μm radius tin grains were observed as the temperature was swept through the superheated superconducting-normal phase transition. In the second test, we were able to observe transitions induced by 90 keV γ-rays in a colloid of 5μmm radius grains in epoxy.
