The Atacama Cosmology Telescope: Passband Measurements with an Analysis of Systematic Errors
Thomas Alford, Rahul Datta, Erminia Calabrese +14
We present measurements of the spectral response of the four Advanced ACTPol (AdvACT) multichroic detector arrays, which observed in frequency bands centered near 30, 40, 90, 150,…
An upgraded frequency-selectable laser source (FLS) calibrator for CMB bandpass characterization
Lauren J. Saunders, Sara M. Simon, Shreya Sutariya +4
One of the biggest challenges for Cosmic Microwave Background (CMB) experiments comes from the uncertainty in instrument bandpass calibration. Uncertainties in bandpass can limit f…
In-Band Scattering and Absorption of Infrared Blocking Foam Filters for Millimeter-wave Cameras
Alex Thomas, Bugao Zou, Shreya Sutariya +11
Expanded closed-cell polymer foams are widely used as thermal infrared (IR) blocking filters in millimeter-wave cameras, particularly for Cosmic Microwave Background observations.…
Superfluid-tight cryogenic receiver with continuous sub-Kelvin cooling for EXCLAIM
Sumit Dahal, Peter A. R. Ade, Christopher J. Anderson +67
The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is a balloon-borne telescope designed to survey star formation over cosmological time scales using intensity…
Simons Observatory: Pre-deployment Performance of a Large Aperture Telescope Optics Tube in the 90 and 150 GHz Spectral Bands
Carlos E. Sierra, Kathleen Harrington, Shreya Sutariya +42
The Simons Observatory will map the temperature and polarization over half of the sky, at millimeter wavelengths in six spectral bands from the Atacama Desert in Chile. These data…
The Simons Observatory: Design, integration, and testing of the small aperture telescopes
Nicholas Galitzki, Tran Tsan, Jake Spisak +77
The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment that includes small-aperture telescopes (SATs) observing from an altitude of 5,200 m in the Ata…
The Simons Observatory: Development and Optical Evaluation of Achromatic Half-Wave Plates
Junna Sugiyama, Tomoki Terasaki, Kana Sakaguri +16
The Simons Observatory (SO) experiment is a cosmic microwave background (CMB) experiment located in the Atacama Desert, Chile. The SO' s small aperture telescopes (SATs) consist of…
Conceptual Design of the Modular Detector and Readout System for the CMB-S4 survey experiment
D. R. Barron, Z. Ahmed, J. Aguilar +47
We present the conceptual design of the modular detector and readout system for the Cosmic Microwave Background Stage 4 (CMB-S4) ground-based survey experiment. CMB-S4 will map the…
Optical Design of the EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM)
Thomas Essinger-Hileman, Danny Chmaytelli, Trevor Oxholm +23
This work describes the design and implementation of optics for EXCLAIM, the EXperiment for Cryogenic Large-Aperture Intensity Mapping. EXCLAIM is a balloon-borne telescope that wi…
Demonstration of 220/280 GHz Multichroic Feedhorn-Coupled TES Polarimeter
Samantha Walker, Carlos E. Sierra, Jason E. Austermann +11
We describe the design and measurement of feedhorn-coupled, transition-edge sensor (TES) polarimeters with two passbands centered at 220 GHz and 280 GHz, intended for observations…
Measuring Reionization, Neutrino Mass, and Cosmic Inflation with BFORE
Sean Bryan, Peter Ade, J. Richard Bond +21
BFORE is a NASA high-altitude ultra-long-duration balloon mission proposed to measure the cosmic microwave background (CMB) across half the sky during a 28-day mid-latitude flight…
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,…
