BICEP/Keck XXII: Analysis of the South Pole Atmosphere for CMB Observations
P. A. R. Ade, Z. Ahmed, M. Amiri +92
The South Pole is among the driest sites on Earth, and the resulting high atmospheric transparency makes it an excellent site for millimeter-wave astronomical observations. Neverth…
Engineering of titanium transition edge sensor wafers for the BA4-90/150 receiver of BICEP Array
A. Patel, P. A. R. Ade, Z. Ahmed +83
BA4-90/150, the fourth receiver to be deployed in the BICEP Array (BA) series, is a dichroic 90/150 GHz instrument targeting the frequency space where sensitivity to the CMB polari…
Advanced Time-Division Multiplexed Readout Chain for the BICEP Array 90/150 GHz Receiver
B. Cantrall, P. A. R. Ade, Z. Ahmed +89
This work presents the current performance of the advanced time-division multiplexed (TDM) readout chain for the BICEP Array 90/150 GHz receiver. BA4-90/150, scheduled for deployme…
Aliased noise characterization and mitigation in BICEP Array 150, 220 and 270 GHz time-division multiplexed detectors
S. Fatigoni, P. A. R. Ade, Z. Ahmed +83
Early observations with the BICEP Array 150 GHz (BA2-150) and 220/270 GHz (BA3-220/270) receivers revealed detector noise equivalent temperatures (NETs) higher than expected, toget…
