Abstract
A superconducting transition edge bolometer is constructed using high critical temperature conducting films by stabilizing a substrate of magnesium oxide or sapphire with a silicon base that is bonded to the substrate using a thermally conductive bonding layer. The base is etched away in the region of the desired radiation detecting portion of the superconductor establishing a controlled thermal connection between the detecting portion and the base which base serves as a thermal bath for the bolometer.
