Microwave Kinetic Inductance Detectors (MKIDs or KIDs)Quasiparticle creation changes the kinetic inductance (surface reactance) of superconductor.Making the superconducting film part of a resonant circuit, capacitively coupled to a through line, results inchange of amplitude and phase of a microwave probe signal→ Very sensitive® Easy frequency-domain multiplexing in the GHz rangeMKID16-pixel arrayPixel designEach pixel has a 16-slot phased array antennaCamera with 16 tiles of 36-4color pixels under construction(Caltech Submillimeter Observatory)• 576 pixels, 2304 resonators, 8 coax + HEMT
