Thermal and Electrical Properties of Prototype Readout Components for CMB-S4
Wilber Dominguez, Darcy R. Barron, Zeeshan Ahmed +11
CMB-S4 is the fourth-generation ground-based cosmic microwave background project, designed to probe the early universe and cosmic inflation. CMB-S4 would achieve its science goals…
The Simons Observatory: Studies of Phase Drift in RF Transmission Lines from the First Large-Scale Deployment of Microwave Frequency Multiplexing for Cosmology
Thomas P. Satterthwaite, Zeeshan Ahmed, Cody J. Duell +4
Fulfilling the science goals of the Simons Observatory, a state-of-the-art cosmic microwave background (CMB) experiment, has required deploying tens of thousands of superconducting…
Simons Observatory: Characterization of the Large Aperture Telescope Receiver
Tanay Bhandarkar, Saianeesh K. Haridas, Jeff Iuliano +41
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that currently consists of three 0.42m small-aperture telescopes (SATs) and one 6m…
The Simons Observatory: Dark Characterization of the Large Aperture Telescope
Saianeesh K. Haridas, Zeeshan Ahmed, Tanay Bhandarkar +20
The Simons Observatory (SO) is a cosmic microwave background experiment composed of three 0.42 m Small Aperture Telescopes (SATs) and one 6 m Large Aperture Telescope (LAT) in the…
The Precursor Small Aperture Telescope (PreSAT) CMB polarimeter
Matthew A. Petroff, Zeeshan Ahmed, James J. Bock +14
The search for the polarized imprint of primordial gravitational waves in the cosmic microwave background (CMB) as direct evidence of cosmic inflation requires exquisite sensitivit…
Development of RFSoC-based direct sampling highly multiplexed microwave SQUID readout for future CMB and submillimeter surveys
Chao Liu, Zeeshan Ahmed, Shawn W. Henderson +3
The SLAC Microresonator Radio Frequency (SMuRF) electronics is being deployed as the readout for the Cosmic Microwave Background (CMB) telescopes of the Simons Observatory (SO). A…
