Abstract:
High-Tc Superconductor Bolometer Arrays
The project objective will be to advance recent developments that apply high-Tc superconductor
films to infrared bolometric detectors. If such detectors are to be useful, 1/f noise
must be minimized, and improved thermal isolation methods must be developed. Superconductor
films and improved metal contacts will be deposited by ion-beam sputtering. To lower
the heat capacity of the detector structure, a new technique that the firm has developed
will be utilized for substrate processing. The technique produces ultrathin but sturdy
membranes. This concept is compatible with subsequent development of linear or rectangular
detector arrays.
The primary application is to infrared radiation detection in spaceborne and ground-based
instruments. Potential applications will initially utilize single-element detectors
and later utilize linear and rectangular arrays.
