Crosstalk Reduction for Superconducting Microwave Resonator Arrays

Crosstalk Reduction for Superconducting Microwave Resonator Arrays

Large-scale arrays of Microwave Kinetic Inductance Detectors (MKIDs) are attractive candidates for use in imaging instruments for next generation submillimeter-wave telescopes such as CCAT. We have designed and fabricated tightly packed ~250-pixel MKID arrays using lumped-element resonators etched from a thin layer of superconducting TiNx deposited on a silicon substrate. …
