Abstract
A radiation detector comprising an element made of superconductive material supplied by an electrical generator as well as a system to measure the resistance of the element. For example, the generator is a constant voltage source. The measuring system utilizes a resistor placed in series with the superconductive element and a voltage measuring apparatus connected to the terminals of the resistor. Incident radiation has the effect of causing variations in the resistance of the superconductive element. Consequently, from the value of the resistance of the superconductive element, the intensity of the radiation received is detected. The disclosed device can be applied to the detection of radiation located between the visible wavelengths and the dwarf wavelengths.
