Scientific paper

Two topics on our recent investigations into superconducting tunnel junction (STJ) detectors are discussed: the single Nb/Al-AlO(x)/Al/Nb junction for high-resolution X-ray detection and the series-connected superconducting tunnel junction detectors (SCSDs) with high detection efficiency. Using a single Nb/Al-AlO(x)/Al/Nb junction with rather large area of 178 x 178 sq microns, we obtained a high energy resolution of 88 eV for 5.9-keV X-rays. The signal-to-noise ratio of the SCSD is discussed from a simple theoretical formulation of electronics, showing that the series-connected STJs can developed as a nuclear radiation detector both with high energy resolution and high efficiency. Recent experimental results of our SCSD are also given.
