According to recent research from Braunschweig, Germany, "Josephson junctions from the high-temperature superconductor YBa2Cu3O7 are routinely used on a cantilever to detect spatially resolved microwave emission from room temperature microwave devices. The Josephson junctions are operated in a temperature range between 40 K to 80 K cooled by a cryo-cooler."
"Near field imaging is accomplished with operating distances of the cooled Josephson cantilever to the surface of the device under test down to 15 mu m. Due to the realization as an active cantilever, a topographic image of the device under test as well as the microwave power distribution can be obtained. We ...
