Planar Antenna-Coupled Bolometers for CMB Polarimetry

Antenna-coupled detectors provide all the functions required of a CMB polarimeter, including beam formation, spectral band definition, and polarization analysis. Planar antennas are fully lithographed devices that do not require coupling optics, and thus readily scale to the production of large focal plane arrays. Antennas coupled to direct detectors such as transitionedge bolometers can realiz...

Some sources of systematic errors on CMB polarized measurements with bolometers

Some sources of systematic errors, specific to polarized CMB measurements using bolometers, are examined. Although the evaluations we show have been made in the context of the Planck mission (and more specifically the Planck HFI), many of our conclusions are valid for other experiments as well. 1 The specifics of CMB polarization signals CMB fluctuations are difficult to measure because of thei...

PUBLICATION III Submillimeter-wave kinetic inductance bolometers on free-standing nanomembranes

We introduce a microwave submillimeter-wave detector based on an integrated micromesh absorber and superconducting kinetic inductance thermometer on a through-wafer released sub-micron thick membrane. Equilibrium operation achieved by thermal isolation through the membrane geometry enables operation at elevated thermal bath temperatures of 5–10 K. The bolometer operates in a phonon-noise limite...
