Multimode bolometer development for the PIXIE instrument
Peter C. Nagler, Kevin T. Crowley, Kevin L. Denis +6
The Primordial Inflation Explorer (PIXIE) is an Explorer-class mission concept designed to measure the polarization and absolute intensity of the cosmic microwave background. In th…
The Atacama Cosmology Telescope: Two-Season ACTPol Spectra and Parameters
Thibaut Louis, Emily Grace, Matthew Hasselfield +80
We present the temperature and polarization angular power spectra measured by the Atacama Cosmology Telescope Polarimeter (ACTPol). We analyze night-time data collected during 2013…
Readout of two-kilopixel transition-edge sensor arrays for Advanced ACTPol
Shawn W. Henderson, Jason R. Stevens, Mandana Amiri +30
Advanced ACTPol is an instrument upgrade for the six-meter Atacama Cosmology Telescope (ACT) designed to measure the cosmic microwave background (CMB) temperature and polarization…
Mechanical design and development of TES bolometer detector arrays for the Advanced ACTPol experiment
Jonathan T. Ward, Jason Austermann, James A. Beall +27
The next generation Advanced ACTPol (AdvACT) experiment is currently underway and will consist of four Transition Edge Sensor (TES) bolometer arrays, with three operating together,…
Survey strategy optimization for the Atacama Cosmology Telescope
F. De Bernardis, J. R. Stevens, M. Hasselfield +34
In recent years there have been significant improvements in the sensitivity and the angular resolution of the instruments dedicated to the observation of the Cosmic Microwave Backg…
Systematic effects from an ambient-temperature, continuously-rotating half-wave plate
T. Essinger-Hileman, A. Kusaka, J. W. Appel +10
We present an evaluation of systematic effects associated with a continuously-rotating, ambient-temperature half-wave plate (HWP) based on two seasons of data from the Atacama B-Mo…
