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…
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…
The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky
William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden +151
Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compt…
The Atacama Cosmology Telescope: Mitigating the impact of extragalactic foregrounds for the DR6 CMB lensing analysis
Niall MacCrann, Blake D. Sherwin, Frank J. Qu +47
We investigate the impact and mitigation of extragalactic foregrounds for the CMB lensing power spectrum analysis of Atacama Cosmology Telescope (ACT) data release 6 (DR6) data. Tw…
Improved microwave SQUID multiplexer readout using a kinetic-inductance traveling-wave parametric amplifier
M. Malnou, J. A. B. Mates, M. R. Vissers +5
We report on the use of a kinetic-inductance traveling-wave parametric amplifier (KITWPA) as the first amplifier in the readout chain of a microwave superconducting quantum interfe…
G4CMP: Condensed Matter Physics Simulation Using the Geant4 Toolkit
M. H. Kelsey, R. Agnese, Y. F. Alam +44
G4CMP simulates phonon and charge transport in cryogenic semiconductor crystals using the Geant4 toolkit. The transport code is capable of simulating the propagation of acoustic ph…
