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…
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…
The Simons Observatory: Studies of Detector Yield and Readout Noise From the First Large-Scale Deployment of Microwave Multiplexing at the Large Aperture Telescope
Thomas P. Satterthwaite, Zeeshan Ahmed, Kyuyoung Bae +21
The Simons Observatory is a new ground-based cosmic microwave background experiment, which is currently being commissioned in Chile's Atacama Desert. During its survey, the observa…
End-to-End Modeling of the TDM Readout System for CMB-S4
David C. Goldfinger, Zeeshan Ahmed, Darcy R. Barron +13
The CMB-S4 experiment is developing next-generation ground-based microwave telescopes to observe the Cosmic Microwave Background with unprecedented sensitivity. This will require a…
Higher Order Nyquist Zone Sampling with RFSoC Data Converters for Astronomical and High Energy Physics Readout Systems
Chao Liu, Zeeshan Ahmed, Shawn W. Henderson +2
From generation to generation, the maximum RF frequency and sampling rate of the integrated data converters in RF system-on-chip (RFSoC) family devices from Xilinx increases signif…
Phase Drift Monitoring for Tone Tracking Readout of Superconducting Microwave Resonators
Max Silva-Feaver, Zeeshan Ahmed, Kam Arnold +5
A number of modern millimeter, sub-millimeter, and far-infrared detectors are read out using superconducting microwave (1-10GHz) resonators. The main detector technologies are Tran…
