Abstract
A cryogenic detector device includes a sensor based on a low-temperature effect and measures the temperature increase produced by the introduction of energy, such as an X-ray quantum. The smaller the thermal capacity of the sensor, the greater the temperature increase resulting from the introduction of energy and the higher the energy resolution of the sensor. Because the thermal capacity is temperature dependent, the sensor is operated in the range of comparatively small thermal capacities, i.e., in a range between 50 and 400 mK. Contrary to conventional assumptions, it was found that by keeping the three-dimensional size of the individual sensors sufficiently small and by increasing the effective sensor area, acceptable measurement results were achieved even at higher operating temperatures of the sensors in a range between 2.4 and 4.2 degrees Kelvin.
