“…YBCO microwave devices, such as microstrip resonators, [8][9][10] have demonstrated low surface resistance and high quality factors at 77 K and frequencies of a few GHz. We therefore expect the problem with feedline transmission and low Q at higher temperatures, which is most significant in array "B," to be solvable with further investigation, allowing future devices to be operable at higher temperatures.…”

“…The devices are fabricated out of YBCO in order to operate at temperatures near 50 K while remaining well below the transition temperature of the superconductor, 90 K. Measurements of thin film YBCO resonators [8][9][10] show that resonators with quality factors in the thousands are plausible, even at temperatures well above 50 K, making it possible to array hundreds of resonators on a single feedline. YBCO bolometers are expected to offer much higher sensitivity than room temperature detectors.…”

We are developing of arrays of membrane isolated resonator-bolometers, each with a kinetic inductance device (KID) to measure the temperature of the membrane. The KIDs are fabricated out of the high temperature superconductor YBCO to allow operation at relatively high temperatures. The bolometers are designed to offer higher sensitivity than sensors operating at 300 K, but they require less expensive and lighter weight cooling than even more sensitive conventional superconducting detectors operating at lower temperatures. The bolometer arrays are applicable as focal planes in infrared imaging spectrometers, such as for planetary science missions or earth observing satellites. We describe the devices and present measurements of their sensitivity.
