Improved Absolute Polarization Calibrator for BICEP CMB Polarimeters
A. R. Polish, P. A. R. Ade, Z. Ahmed +89
Cosmic birefringence is a hypothesized parity violation in electromagnetism that predicts a frequency-independent polarization rotation as light propagates. This would rotate the l…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
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…
2022 Upgrade and Improved Low Frequency Camera Sensitivity for CMB Observation at the South Pole
A. Soliman, P. A. R. Ade, Z. Ahmed +83
Constraining the Galactic foregrounds with multi-frequency Cosmic Microwave Background (CMB) observations is an essential step towards ultimately reaching the sensitivity to measur…
Plastic Laminate Antireflective Coatings for Millimeter-wave Optics in BICEP Array
Marion Dierickx, P. A. R. Ade, Zeeshan Ahmed +82
The BICEP/Keck series of experiments target the Cosmic Microwave Background at degree-scale resolution from the South Pole. Over the next few years, the "Stage-3" BICEP Array (BA)…
Magnetic Sensitivity of AlMn TESes and Shielding Considerations for Next-Generation CMB Surveys
E. M. Vavagiakis, S. W. Henderson, K. Zheng +17
In the next decade, new ground-based Cosmic Microwave Background (CMB) experiments such as Simons Observatory (SO), CCAT-prime, and CMB-S4 will increase the number of detectors obs…
A Study of Al-Mn Transition Edge Sensor Engineering for Stability
E. M. George, J. E. Austermann, J. A. Beall +32
The stability of Al-Mn transition edge sensor (TES) bolometers is studied as we vary the engineered TES transition, heat capacity, and/or coupling between the heat capacity and TES…
Multi-Chroic Feed-Horn Coupled TES Polarimeters
J. McMahon, J. Beall, D. Becker +8
Multi-chroic polarization sensitive detectors offer an avenue to increase both the spectral coverage and sensitivity of instruments optimized for observations of the cosmic-microwa…
