Photon-noise limited sensitivity in titanium nitride kinetic inductance detectors

Johannes Hubmayr, James A. Beall, Daniel T. Becker, Hsiao-Mei Cho, Gene C. Hilton, Dale Li, David P. Pappas, Jeffrey L. Van Lanen, Mark Devlin, Kent D. Irwin, Chris Groppi, Phillip Mauskopf
We demonstrate photon-noise limited performance at sub-millimeter wavelengths in microwave kinetic inductance detectors (MKIDs) made of a new superconducting

Properties of TiN for Detector and Amplifier Applications

Jiansong Gao, Michael R. Vissers, Martin O. Sandberg, Dale Li, Hsiao-Mei Cho, Clint Bockstiegel, Ben Mazin, Henry G. Leduc, Saptarshi Chaudhuri, David P. Pappas, K D. Irwin
We have experimentally explored and carefully characterized the important properties of TiN, including the resistivity, nonlinear kinetic inductance, the

Improvements in silicon oxide dielectric loss for superconducting microwave detector circuits

Dale Li, Jason Austermann, James A. Beall, Daniel T. Becker, Hsiao-Mei Cho, Anna E. Fox, Nils Halverson, Jason Henning, Gene C. Hilton, Johannes Hubmayr, Jeffrey L. Van Lanen, John P. Nibarger, Michael D. Niemack, Kent D. Irwin
Dielectric loss in low-temperature superconducting integrated circuits can cause lower overall efficiency, particularly in the 90 to 220 GHz regime. We present

Dual-polarization sensitive MKIDs for far infrared astrophysics

Johannes Hubmayr, James A. Beall, Daniel T. Becker, Hsiao-Mei Cho, Brad Dober, Mark Devlin, Anna E. Fox, Dale Li, Michael D. Niemack, David P. Pappas, Leila R. Vale, Kent D. Irwin, Gene C. Hilton
We present the design for arrays of dual-polarization sensitive, superconducting sensors for far infrared astrophysics. Each pixel is feedhorn-coupled and
