Cosmology Large Angular Scale Surveyor (CLASS) Focal Plane Development
D. T. Chuss, A. Ali, M. Amiri +28
The Cosmology Large Angular Scale Surveyor (CLASS) will measure the polarization of the Cosmic Microwave Background to search for and characterize the polarized signature of inflat…
Design and Deployment of a Multichroic Polarimeter Array on the Atacama Cosmology Telescope
R. Datta, J. Austermann, J. A. Beall +28
We present the design and the preliminary on sky performance with respect to beams and pass-bands of a multichroic polarimeter array covering the 90 and 146 GHz Cosmic Microwave Ba…
Evidence for the kinematic Sunyaev-Zeľdovich effect with ACTPol and velocity reconstruction from BOSS
Emmanuel Schaan, Simone Ferraro, Mariana Vargas-Magaña +43
We use microwave temperature maps from two seasons of data from the Atacama Cosmology Telescope (ACTPol) at 146 GHz, together with the Constant Mass CMASS galaxy sample from the Ba…
Advanced ACTPol Cryogenic Detector Arrays and Readout
S. W. Henderson, R. Allison, J. Austermann +54
Advanced ACTPol is a polarization-sensitive upgrade for the 6 m aperture Atacama Cosmology Telescope (ACT), adding new frequencies and increasing sensitivity over the previous ACTP…
BFORE: The B-mode Foreground Experiment
Michael D. Niemack, Peter Ade, Francesco de Bernardis +19
The B-mode Foreground Experiment (BFORE) is a proposed NASA balloon project designed to make optimal use of the sub-orbital platform by concentrating on three dust foreground bands…
Frequency-tunable Superconducting Resonators via Nonlinear Kinetic Inductance
Michael R. Vissers, Johannes Hubmayr, Martin Sandberg +3
We have designed, fabricated and tested a frequency-tunable high-Q superconducting resonator made from a niobium titanium nitride film. The frequency tunability is achieved by inje…
