Superconducting tunnel junction (STJ) detectors have great potential as ultra-high energy-resolution detectors even at high count rates of over 10 4 counts per second. In fact, single-junction detectors showed energy resolutions of better than 30 eV for 5.9 keV x-rays, 6 eV for 277 eV x-rays and 0.2

β¦ Synopsis
Sublimated thin films of InxOy and thermally oxidized indium films have been used as barriers in the fabrication of crossed-film tunnelling junctions, whose characteristics can be controlled by varying the thickness of the deposited barrier. Josephson junctions of varying current densities, as well as junctions exhibiting only single-particle tunnelling characteristics, have been fabricated.

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 100Γ100 Β΅m was illuminated, while a slit mask of about 150 Β΅m width was used to shadow the detector leads and subst
## Superconducting tunnel junction (STJ) detectors have potential as ultra-high-energy resolution detectors. Recently, single-junction detectors, where radiation is directly absorbed and detected by an STJ, have shown much higher energy resolutions than semiconductor detectors even at high count ra
