The SPT-3G+ receiver design
H. Athreya, Z. Ahmed, J. E. Austermann +71
We present the thermo-mechanical design of the cryostat and camera optics for SPT-3G+, a new receiver being developed for the South Pole Telescope (SPT). The receiver consists of 1…
Map Multi-Tool: A Map-Based Approach to Modeling Beam Systematics for Cosmic Microwave Background Experiments
Cesiley L. King, Alec Hryciuk, Jeff McMahon +2
Cosmic microwave background (CMB) experiments use simulations of instrumental systematic effects to ensure high-fidelity measurements of cosmological parameters. Quantifying the ex…
picoMUX: microcontroller based time-domain multiplexing readout for kilopixel TES arrays
Simon Tartakovsky, Alexandre E. Adler, Jason E. Austermann +23
Advances in cryogenic SQUID-based time-domain multiplexing (TDM) have outpaced their warm readout electronics. Next generation CMB telescopes are baselining kilopixel TES arrays wi…
Sub-Kelvin Cryogenics for a Super-Pressure Balloon-Borne CMB Polarimeter: Taurus
Jared L. May, Alexandre E. Adler, Jason E. Austermann +23
Taurus is a balloon-borne cosmic microwave background (CMB) experiment designed to operate more than 10,000 transition-edge sensor bolometers at a base temperature near 100 mK duri…
In-Flight Performance of Spider's 280 GHz Receivers
Elle C. Shaw, P. A. R. Ade, S. Akers +84
SPIDER is a balloon-borne instrument designed to map the cosmic microwave background at degree-angular scales in the presence of Galactic foregrounds. SPIDER has mapped a large sky…
Overview of the Optical Design of the CMB-S4 Large Aperture Telescopes and Camera Optics
Patricio A. Gallardo, Kathleen Harrington, Roberto Puddu +8
CMB-S4, the next-generation CMB observatory, will deploy hundreds of thousands of detectors to enable mapping the millimeter-wavelength sky with unprecedented speed. The large aper…
Freeform three-mirror anastigmatic large-aperture telescope and receiver optics for CMB-S4
Patricio A. Gallardo, Roberto Puddu, Kathleen Harrington +14
CMB-S4, the next-generation ground-based cosmic microwave background (CMB) observatory, will provide detailed maps of the CMB at millimeter wavelengths to dramatically advance our…
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…
Design and characterization of the SPT-3G receiver
J. A. Sobrin, P. A. R. Ade, Z. Ahmed +68
The SPT-3G receiver was commissioned in early 2017 on the 10-meter South Pole Telescope (SPT) to map anisotropies in the cosmic microwave background (CMB). New optics, detector, an…
Broadband anti-reflective coatings for cosmic microwave background experiments
A. Nadolski, A. M. Kofman, J. D. Vieira +71
The desire for higher sensitivity has driven ground-based cosmic microwave background (CMB) experiments to employ ever larger focal planes, which in turn require larger reimaging o…
Pointing control for the SPIDER balloon-borne telescope
Jamil A. Shariff, Peter A. R. Ade, Mandana Amiri +45
We present the technology and control methods developed for the pointing system of the SPIDER experiment. SPIDER is a balloon-borne polarimeter designed to detect the imprint of pr…
Modeling and characterization of the SPIDER half-wave plate
Sean A. Bryan, Peter A. R. Ade, Mandana Amiri +42
Spider is a balloon-borne array of six telescopes that will observe the Cosmic Microwave Background. The 2624 antenna-coupled bolometers in the instrument will make a polarization…
