| Abstract(in English) | Microwave Kinetic Inductance Detector (MKID) camera has been developed at National Astronomical Observatory of Japan for millimeter-wave and terahertz astronomy. MKID composed of superconducting resonators can sense a number of quasi-particles which incident photons above the gap energy generate by breaking Cooper pairs. A bi-layer MKID such as Al/Nb is attractive because the gap energy or the threshold frequency is easily changed due to proximity effect. It is quite useful for space observatory or a remote site such as the Antarctica where power consumption of cryocoolers is severely limited. We report high quality resonators of bi-layer (Al/Nb) MKIDs fabricated by liftoff technique. And we found temperature dependence of bi -layer MKID quality factor showed different behavior as Al or Nb monolayer. |
