Response of Nb-based tunnel junctions to synchrotron radiation

Superconducting tunnel junctions have potential high energy-resolution for X-ray detection. The excellent performance may be suited for experiments making use of X-rays from a synchrotron radiation. The characteristics of the Nb-based junction were studied to know the response of Nb-based junctions to the synchrotron radiation. We obtained the dependence of the detector pulse height on X-ray energies in a range of 4 to 15 keV.<
