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…
Quantifying the systematic impact of differential beam response on the BICEP CMB polarization data from 2016 through 2024
B. D. Elwood, P. A. R. Ade, Z. Ahmed +83
As cosmic microwave background (CMB) polarization experiments, including BICEP3, BICEP Array, and future BICEP experiments, achieve ever-deeper polarization maps in search of primo…
Optics and broadband anti-reflection coatings for the BA4-90/150 receiver
A. R. Polish, P. A. R. Ade, Z. Ahmed +84
The BICEP Array telescopes search for primordial B-mode polarization from inflationary gravitational waves. This signal is exceedingly faint, demanding excellent map depth and syst…
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…
Optical characterization of the BICEP array 150 and 220/270GHz CMB polarimeters in the 2026 season
M. Izquierdo Poza, P. A. R. Ade, Z. Ahmed +82
BICEP Array (BA) is the current-generation instrument in the BICEP series of small-aperture, on-axis refracting telescopes at the South Pole, designed to constrain the tensor-to-sc…
Fabry-Pérot open resonant cavities for measuring the dielectric parameters of mm-wave optical materials
Brodi D. Elwood, Paul K. Grimes, John Kovac +2
As millimeter-wave cosmology experiments refine their optical chains, precisely characterizing their optical materials under cryogenic conditions becomes increasingly important. Fo…
Multi-layer anti-reflection coats using ePTFE membrane for mm-wavelength plastic optics
Miranda Eiben, Keara Carter, Marion Dierickx +7
Future millimeter wavelength experiments aim to both increase aperture diameters and broaden bandwidths to increase the sensitivity of the receivers. These changes produce a challe…
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…
Conceptual Design of the Modular Detector and Readout System for the CMB-S4 survey experiment
D. R. Barron, Z. Ahmed, J. Aguilar +47
We present the conceptual design of the modular detector and readout system for the Cosmic Microwave Background Stage 4 (CMB-S4) ground-based survey experiment. CMB-S4 will map the…
