Performance of a low-parasitic frequency-domain multiplexing readout
A. E. Lowitz, A. N. Bender, P. Barry +14
Frequency-domain multiplexing is a readout technique for transition edge sensor bolometer arrays used on modern CMB experiments, including the SPT-3G receiver. Here, we present des…
Year two instrument status of the SPT-3G cosmic microwave background receiver
A. N. Bender, P. A. R. Ade, Z. Ahmed +86
The South Pole Telescope (SPT) is a millimeter-wavelength telescope designed for high-precision measurements of the cosmic microwave background (CMB). The SPT measures both the tem…
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…
The Dark Energy Camera
B. Flaugher, H. T. Diehl, K. Honscheid +115
The Dark Energy Camera is a new imager with a 2.2-degree diameter field of view mounted at the prime focus of the Victor M. Blanco 4-meter telescope on Cerro Tololo near La Serena,…
