A novel radiation detector, the Intrinsic Superconducting Radiation Detector (ISRD), is proposed. It employs the temperature dependence of the critical current of high T, superconducting films to determine the detector temperature change caused by incident radiation and operates almost exclusively in the superconducting state. The ISRD has the potential to be a phonon-noise-limited thermal detector.
