Superconducting series-junction detectors present the possibility of highly practical radiation detectors with high detection efficiencies, high count rates, and high energy-resolution even for radiation that is difficult to detect efficiently with traditional radiation detectors. A series-junction detector with an effective volume of 8×8×0.4 mm3 has shown that the efficiency of signal charge production is high despite its large volume. The position dependence of signal heights of a series-junction detector with an effective area of 1.5×1.5 mm2 was corrected, and the energy resolution was improved from 2.9% to 0.42%.
