BICEP/Keck XIX: Extremely Thin Composite Polymer Vacuum Windows for BICEP and Other High Throughput Millimeter Wave Telescopes
Keck Collaboration, P. A. R. Ade, Z. Ahmed +90
Millimeter-wave refracting telescopes targeting the degree-scale structure of the cosmic microwave background (CMB) have recently grown to diffraction-limited apertures of over 0.5…
BICEP/Keck XVIII: Measurement of BICEP3 polarization angles and consequences for constraining cosmic birefringence and inflation
Keck Collaboration, P. A. R. Ade, Z. Ahmed +83
We use a custom-made calibrator to measure individual detectors' polarization angles of BICEP3, a small aperture telescope observing the cosmic microwave background (CMB) at 95GHz…
Calibration Measurements of the BICEP3 and BICEP Array CMB Polarimeters from 2017 to 2024
Christos Giannakopoulos, Clara Vergès, P. A. R. Ade +83
The BICEP3 and BICEP Array polarimeters are small-aperture refracting telescopes located at the South Pole designed to measure primordial gravitational wave signatures in the Cosmi…
Development of the 220/270 GHz Receiver of BICEP Array
Keck Collaboration, Y. Nakato, P. A. R. Ade +82
Measurements of B-mode polarization in the CMB sourced from primordial gravitational waves would provide information on the energy scale of inflation and its potential form. To ach…
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…
Beam Maps of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Measured with a Drone
Will Tyndall, Alex Reda, J. Richard Shaw +14
We present beam measurements of the CHIME telescope using a radio calibration source deployed on a drone payload. During test flights, the pulsing calibration source and the telesc…
Constraining Inflation with the BICEP/Keck CMB Polarization Experiments
Keck Collaboration, P. A. R. Ade, Z. Ahmed +84
The BICEP/ (BK) series of cosmic microwave background (CMB) polarization experiments has, over the past decade and a half, produced a series of field-leading constra…
