Abstract: Results from tests of several Nb thin film microstrip superconducting detectors are reported. A preliminary measurement of critical radius of the hot spot generated by 5 MeV alpha -particles is compared with simple model predictions. An effort is made to understand and measure the propagation characteristics of the superconducting to normal transition along the strip. For this purpose, fast current pulses are injected into the strip, and the voltage drop is observed with a digital scope. >
