Abstract
Measurements of the x ray response of niobium-based superconducting tunnel junctions with Al trapping layers are presented. Signal amplitudes equivalent to as many as 2.3 multiplied by 108 tunneled electrons for a 5.9 keV photon are observed, corresponding to an amplification factor of approximately 100 per initially created quasiparticle in niobium. The detectors, however, exhibit a significant non-linearity in their energy response. The energy resolution is approximately 140 eV FWHM at 5.9 keV.
