2. A Nb single crystal X-ray detector read out by superconductive tunnel junctions

Author

van der Berg, M.L., Kiewiet, F.B., Bruijn, M.P., Luiten, O.J., de Korte, P.A.J., Martin, J., and Huebener, R.P.

Subjects
Detectors -- Design and construction, Niobium -- Usage, Superconductive devices -- Design and construction, X-ray spectroscopy -- Equipment and supplies, Business, Electronics, Electronics and electrical industries
Abstract

The fabrication of a prototype imaging X-ray detector is presented. The detector is composed of aluminum/aluminum oxide/aluminum/niobium superconductive tunnel junctions sputtered directly on a high purity niobium single crystal with an RRR of about 15000. The detector has the potential to offer high energy resolution in addition to a high quantum efficiency, large detection area and improved imaging capabilities. The spatial and temporal response of the detector has already been derived.

Abstract

A study analyzes the development of the infrared/sub-mm bolometer beginning with a synopsis of relevant bolometer theory and its most significant parameters. It proposes a fabrication process for a fully integrated bolometer comprising an absorber, a thermometer and suspension structure based on micro machining of a silicon nitride spiderweb structural membrane and a variety of thin film deposition and etching procedures.

4. Inhomogeneous response of superconducting tunnel junctions with a killed electrode for x-ray spectroscopy

Author

van den Berg, M.L., Bruijn, M.P., Gomez, J., Kiewiet, F.B., de Korte, P.A.J., van Lieshout, H.L., Luiten, O.J., Martin, J., le Grand, J.B., Schroeder, T., and Huebener, R.P.

Subjects
Josephson junction -- Research, Tunneling (Physics) -- Research, X-ray spectroscopy -- Research, Business, Electronics, Electronics and electrical industries
Abstract

Niobium-based superconducting tunnel junctions are proposed for high energy resolution x-ray detectors. Inhomogeneous response, however, results from lateral diffusion and the loss of excess particles at the edges. Detectors with a Ta-trap were developed to analyze the energy resolution degradation. The approach successfully trapped the killed electrode and removed it from the tunneling process.
