Abstract : A summary is presented of the work conducted, and the techniques employed, during the period March 25, 1964, through February 15, 1965, in which the application of superconducting thin films to nuclear particle detection was investigated. The main result of this work is that superconducting nuclear particle detectors are feasible. Self-recovering, alpha-particle induced pulses of nanosec duration have been observed on a variety of tin films which had widths ranging from 10 to 50 microns. Considerable progress has been made in understanding these and other observations by the development of a theory which is in good quantitative agreement with the experimental results.
