Abstract :
Development of cryogenic detectors for hard X-rays and α-particles using superconducting tunnel junctions has been started. Detector chips with series STJ arrays have been fabricated and experiments for evaluation of the chip properties have been carried out. 0.77% of energy resolution in full-width at half-maximum for 5.48 MeV α-particles has been obtained. To the contrary, energy resolutions for hard X-rays have been poor because of bad signal-to-noise ratio.
