Radiation Detection Mechanisms in High Temperature Superconductors
All radiation detection modes in superconductors and superconducting structures can be characterized by the dependence of resistance on temperature, current, or voltage. This allows their performance to be estimated and compared by measuring film resistance as a function of temperature and current. We present measurements of the current dependence of film resistance for high temperature oxide superconductors (HTOS) which indicate a high (> 10KV/W) responsivity for radiation detection. We will relate this high responsivity to resistance mechanisms in these films.
