Description

Superconducting tunnel junction detectors are being developed as both particle and x-ray detectors. Aluminium junctions are suitable for detectors because of their strong native oxide barriers, and because of the small energy gap of aluminium. Aluminium tunnel junction detectors must be operated near 0.1 TC which is 110 mK for aluminium. To operate detectors at these temperatures, adiabatic demagnetization refrigerators (ADRs) for the laboratory and prototype ADRs for space based operation were developed. It was demonstrated that the magnetic field of the ADR need not compromise the performance of aluminium tunnel junctions. (author) 8 refs.; 3 figs
