Dual-polarization sensitive MKIDs for far infrared astrophysics

December 12, 2012

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 consists of orthogonal, lumped-element kinetic inductance detectors (LEKIDs) both fabricated in the

John P. Nibarger, James A. Beall, Daniel T. Becker, Joseph W. Britton, Hsiao-Mei Cho, Anna E. Fox, Gene C. Hilton, Johannes Hubmayr, Dale Li, Kent D. Irwin, Jeffrey L. Van Lanen, Jeff McMahon, Ki Won Yoon
Silicon platelet corrugated feedhorn for cosmic microwave background (CMB) measurements in the mm wave (130 to 170 GHz) have been developed for deployment for the polarization sensitive upgrade to both the Atacama Cosmology Telescope (ACTpol) and the South

Al-Mn transition edge sensors for cosmic microwave background polarimeters

November 22, 2010
Author(s)
Daniel R. Schmidt, Hsiao-Mei Cho, Johannes Hubmayr, Peter J. Lowell, Michael D. Niemack, Galen C. O'Neil, Joel N. Ullom, Ki W. Yoon, Kent D. Irwin
Superconducting transition edge sensors (TES) require superconducting films with transition temperatures (Tc)and properties that can be tailored to the particular requirements of individual applications. We have been developing Al-Mn films with a tunable
