Superconducting Material for IR Detector Arrays

Abstract

This report describes the efforts to develop and evaluate high-T superconducting (HTS) materials for infrared detector arrays. The use of HTS materials and devices in infrared (IR) detectors was motivated by the very long wavelength cutoff at the superconducting energy gap (greater than 40 micron), immunity of superconductors to many radiation environments, and very fast response times. In addition, they offered the potential for Josephson-based preprocessors with analog-to-digital converters (ADC) operating at three orders of magnitude lower power than comparable semiconductors ADCs. Such low-power ADCs are an enabling technology for on-focal-plane (FPA) digitization of IR images and low-noise transfer of digital signals to off-plane images.
