We are developing normal-insulator-superconductor (NIS) tunnel junctions for use as X-ray detectors for astronomical purposes and as phonon sensors for dark matter detectors. We are using photolithographic techniques to produce structures in which aluminum is the superconductor, Al2O3 is the tunnel barrier, and copper is the normal metal. We describe microfabrication details and present X-ray pulse data.
