The POLARBEAR-2 and Simons Array Focal Plane Fabrication Status
B. Westbrook, P. A. R. Ade, M. Aguilar +90
We present on the status of POLARBEAR-2 A (PB2-A) focal plane fabrication. The PB2-A is the first of three telescopes in the Simon Array (SA), which is an array of three cosmic mic…
Development of epoxy-based millimeter absorber with expanded polystyrenes and carbon black
Yuki Inoue, Masaya Hasegawa, Masashi Hazumi +2
We recently developed and characterized an absorber for millimeter wavelengths. To absorb the millimeter wave efficiently, we need to develop the low reflection and high absorption…
Broadband multi-layer anti-reflection coatings with mullite and duroid for half-wave plates and alumina filters for CMB polarimetry
Kana Sakaguri, Masaya Hasegawa, Yuki Sakurai +2
A broadband two-layer anti-reflection (AR) coating was developed for use on a sapphire half-wave plate (HWP) and an alumina infrared (IR) filter for cosmic microwave background (CM…
High-precision temperature monitoring system for room-temperature equipment in astrophysical observations
Daiki Tanabe, Masaya Hasegawa, Masashi Hazumi +5
We present a precise thermometry system to monitor room-temperature components of a telescope for radio-astronomy such as cosmic microwave background (CMB) observation. The system…
Snowmass 2021 CMB-S4 White Paper
Kevork Abazajian, Arwa Abdulghafour, Graeme E. Addison +353
This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin a…
Improved upper limit on degree-scale CMB B-mode polarization power from the 670 square-degree POLARBEAR survey
The POLARBEAR Collaboration, S. Adachi, T. Adkins +51
We report an improved measurement of the degree-scale cosmic microwave background -mode angular-power spectrum over 670 square-degree sky area at 150 GHz with POLARBEAR. In the…
