| Abstract: | We describe the results of experiments on the35S irradiation of a metastable superconducting detector between 2.0 and 3.4 K using a second-derivative rf SQUID readout operated in an integral mode. The detector consisted of 3×106 tin grains, distributed in diameter from 10–25 micron. Comparison with computer simulation based on a hot border model consistent with the measurement protocols yields reasonable agreement despite the large timing uncertainties associated with the measuring systematics of the SQUID system. |
