Thin-film superconducting tunnel junctions (Sn/SnO x /Sn) operated at a temperature of 0.3 K were irradiated by a 55 Fe X-ray source. Pulses due to photo-absorption in the devices were observed and the Mn K α , K β lines at 5.89 keV and 6.49 keV, respectively, could clearly be resolved by pulse-height analysis. An energy resolution of Δ E (FWHM) = 250 eV was obtained in the first tests reported here. Improvements may be possible by straightforward techniques.
