Crosstalk effects in microwave SQUID multiplexed TES bolometer readout
John C. Groh, Zeeshan Ahmed, Shawn W. Henderson +5
Transition-edge sensor (TES) bolometers are broadly used for background-limited astrophysical measurements from the far-infrared to mm-waves. Many planned future instruments requir…
Improved Polarization Calibration of the BICEP3 CMB Polarimeter at the South Pole
J. Cornelison, C. Vergès, P. A. R. Ade +83
The BICEP3 Polarimeter is a small aperture, refracting telescope, dedicated to the observation of the Cosmic Microwave Background (CMB) at 95GHz. It is designed to target degree an…
Thermal Testing for Cryogenic CMB Instrument Optical Design
D. C. Goldfinger, P. A. R. Ade, Z. Ahmed +83
Observations of the Cosmic Microwave Background rely on cryogenic instrumentation with cold detectors, readout, and optics providing the low noise performance and instrumental stab…
A simulation suite for readout with SMuRF tone-tracking electronics
Cyndia Yu, Zeeshan Ahmed, J. Mitch D'Ewart +3
We present the details of a simulation suite for modeling the effects of readout with SLAC Microresonator RF (SMuRF) electronics. The SMuRF electronics are a warm readout and contr…
The Simons Observatory microwave SQUID multiplexing detector module design
Heather McCarrick, Erin Healy, Zeeshan Ahmed +56
Advances in cosmic microwave background (CMB) science depend on increasing the number of sensitive detectors observing the sky. New instruments deploy large arrays of superconducti…
Microwave multiplexing on the Keck Array
Ari Cukierman, Zeeshan Ahmed, Shawn Henderson +82
We describe an on-sky demonstration of a microwave-multiplexing readout system in one of the receivers of the Keck Array, a polarimetry experiment observing the cosmic microwave ba…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
Highly-multiplexed microwave SQUID readout using the SLAC Microresonator Radio Frequency (SMuRF) Electronics for Future CMB and Sub-millimeter Surveys
Shawn W. Henderson, Zeeshan Ahmed, Jason Austermann +29
The next generation of cryogenic CMB and submillimeter cameras under development require densely instrumented sensor arrays to meet their science goals. The readout of large number…
