Abstract
This paper examines the thermal response of a superconductor infrared detector. A simple design is considered that consists of a superconductor film sandwiched between a radiation absorber and a substrate. The substrate is mounted on a heat sink maintained at approximately the midpoint of the superconducting transition temperature range. The rapid change in resistivity in this temperature range is monitored to detect incoming radiation heat. A bias current flows through the superconductor film and the resulting heat transfer equations are highly non-linear due to the complicated Joule heating term. A parametric study is conducted to examine the effects of incoming radiation flux and bias current on the sensitivity and response of the device. The results indicate that the response is a strong function of the bias current.
