✦ Synopsis

Development of cryogenic detectors for hard X-rays and a-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 aparticles has been obtained. To the contrary, energy resolutions for hard X-rays have been poor because of bad signalto-noise ratio.

An energy resolution of 1E = 12 eV (FWHM) was measured for the 55 Mn Ka 1 line (E = 5.90 keV) using a single superconducting Al/Al x O y /Al tunnel junction. The total detector area of 100Γ—100 Β΅m was illuminated, while a slit mask of about 150 Β΅m width was used to shadow the detector leads and subst
