Flat low-loss silicon gradient index lens for millimeter and submillimeter wavelengths
Fabien Defrance, Cecile Jung-Kubiak, Sofia Rahiminejad +6
We present the design, simulation, and planned fabrication process of a flat high resistivity silicon gradient index (GRIN) lens for millimeter and submillimeter wavelengths with v…
BICEP/Keck XXI: Constraints on Early-Universe Parity Violation from Multipole-Dependent Birefringence
Keck Collaboration, P. A. R. Ade, Zeeshan Ahmed +94
We present the first constraints on multipole-dependent cosmic birefringence using CMB polarization data from the BK18 dataset, which combines observations from BICEP2, Keck Array,…
Plastic Laminate Antireflective Coatings for Millimeter-wave Optics in BICEP Array
Marion Dierickx, P. A. R. Ade, Zeeshan Ahmed +82
The BICEP/Keck series of experiments target the Cosmic Microwave Background at degree-scale resolution from the South Pole. Over the next few years, the "Stage-3" BICEP Array (BA)…
The Simons Observatory: Magnetic Shielding Measurements for the Universal Multiplexing Module
Zachary B. Huber, Yaqiong Li, Eve M. Vavagiakis +14
The Simons Observatory (SO) includes four telescopes that will measure the temperature and polarization of the cosmic microwave background using over 60,000 highly sensitive transi…
Assembly development for the Simons Observatory focal plane readout module
Erin Healy, Aamir M. Ali, Kam Arnold +28
The Simons Observatory (SO) is a suite of instruments sensitive to temperature and polarization of the cosmic microwave background (CMB) to be located at Cerro Toco in the Atacama…
The design of the Ali CMB Polarization Telescope receiver
Maria Salatino, Jason E. Austermann, Keith L. Thompson +72
Ali CMB Polarization Telescope (AliCPT-1) is the first CMB degree-scale polarimeter to be deployed on the Tibetan plateau at 5,250m above sea level. AliCPT-1 is a 90/150 GHz 72 cm…
