摘要：
We have developed superconducting, single-photon imaging x-ray detectors with an energy resolution of 26 eV FWHM at 6 keV and a spatial resolution of 0.5 mu m over an effective area of 18 mu m x 100 mu m. The energy resolution is among the best reported for this kind of detector and is within a factor of approximate to 4 of it's theoretical limit. The calculated absorption efficiency of the detector is 28%. Scaling to larger areas and higher quantum efficiency appear possible. We discuss the device design and readout along with possible sources of resolution broadening.
