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
## 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
An analysis is made of current-voltage Characteristics of superconductor-insulatormetal-insulator-superconductor tunnel structures. The I-V-curves depend strongly on the competition between tunneling through the insulators and inelastic scattering in the metal. It is shown that if the metal is a sup
