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…
Application of the independent component analysis to the iKAGRA data
KAGRA Collaboration, T. Akutsu, M. Ando +244
We apply the independent component analysis (ICA) to the real data from a gravitational wave detector for the first time. Specifically we use the iKAGRA data taken in April 2016, a…
Improving the absolute accuracy of the gravitational wave detectors by combining the photon pressure and gravity field calibrators
Yuki Inoue, Sadakazu Haino, Nobuyuki Kanda +5
The absolute accuracy of the estimated parameters of gravitational wave sources will be fundamentally limited by the calibration uncertainties of the detectors in upcoming observat…
Performance of a continuously rotating half-wave plate on the POLARBEAR telescope
Satoru Takakura, Mario Aguilar, Yoshiki Akiba +50
A continuously rotating half-wave plate (CRHWP) is a promising tool to improve the sensitivity to large angular scales in cosmic microwave background (CMB) polarization measurement…
POLARBEAR-2: an instrument for CMB polarization measurements
Y. Inoue, P. Ade, Y. Akiba +83
POLARBEAR-2 (PB-2) is a cosmic microwave background (CMB) polarization experiment that will be located in the Atacama highland in Chile at an altitude of 5200 m. Its science goals…
Making maps of Cosmic Microwave Background polarization for B-mode studies: the POLARBEAR example
Davide Poletti, Giulio Fabbian, Maude Le Jeune +46
Analysis of cosmic microwave background (CMB) datasets typically requires some filtering of the raw time-ordered data. Filtering is frequently used to minimize the impact of low fr…
Two-layer anti-reflection coating with mullite and polyimide foam for large-diameter cryogenic infrared filters
Yuki Inoue, Takaho Hamada, Masaya Hasegawa +8
We have developed a novel two-layer anti-reflection (AR) coating method for large-diameter infrared (IR) filters made of alumina, for the use at cryogenic temperatures in millimete…
Millimeter-Wave Broadband Anti-Reflection Coatings Using Laser Ablation of Sub-Wavelength Structures
Tomotake Matsumura, Karl Young, Qi Wen +7
We report on the first use of laser ablation to make sub-millimeter, broad-band, anti-reflection coatings (ARC) based on sub-wavelength structures (SWS) on alumina and sapphire. We…
The POLARBEAR-2 and the Simons Array Experiment
A. Suzuki, P. Ade, Y. Akiba +86
We present an overview of the design and status of the \Pb-2 and the Simons Array experiments. \Pb-2 is a Cosmic Microwave Background polarimetry experiment which aims to character…
Modeling atmospheric emission for CMB ground-based observations
J. Errard, P. A. R. Ade, Y. Akiba +72
Atmosphere is one of the most important noise sources for ground-based cosmic microwave background (CMB) experiments. By increasing optical loading on the detectors, it amplifies t…
Development and characterization of the readout system for POLARBEAR-2
D. Barron, P. A. R. Ade, Y. Akiba +69
POLARBEAR-2 is a next-generation receiver for precision measurements of the polarization of the cosmic microwave background (Cosmic Microwave Background (CMB)). Scheduled to deploy…
Cryogenic infrared filter made of alumina for use at millimeter wavelength
Yuki Inoue, Tomotake Matsumura, Masashi Hazumi +5
We propose a high thermal conductivity infrared (IR) filter using alumina for use in millimeter wave detection systems. We constructed a prototype two-layer anti-reflection (AR) co…
