Development and characterization of a millimeter-wave circular polarization observation method using a quarter-wave plate with Simons Array
Kana Sakaguri, Darcy R. Barron, Yuji Chinone +17
We have developed and demonstrated a method for measuring circular polarization at 90 GHz by combining a quarter-wave plate (QWP) and a continuously rotating half-wave plate (HWP).…
Development of TIFUUN: Terahertz Integral Field Units with Universal Nanotechnology
Akira Endo, Tom J. L. C. Bakx, Jochem J. A. Baselmans +50
TIFUUN (THz Integral Field Units with Universal Nanotechnology) is an ultra-wideband mm-submm wave imaging spectrometer that capitalizes on the highly scalable integrated supercond…
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…
A measurement of atmospheric circular polarization with POLARBEAR
Takuro Fujino, Satoru Takakura, Shahed Shayan Arani +20
At millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth's magnetic field. We report a measurement…
The Simons Observatory: Design, integration, and testing of the small aperture telescopes
Nicholas Galitzki, Tran Tsan, Jake Spisak +77
The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment that includes small-aperture telescopes (SATs) observing from an altitude of 5,200 m in the Ata…
The Simons Observatory: Development and Optical Evaluation of Achromatic Half-Wave Plates
Junna Sugiyama, Tomoki Terasaki, Kana Sakaguri +16
The Simons Observatory (SO) experiment is a cosmic microwave background (CMB) experiment located in the Atacama Desert, Chile. The SO' s small aperture telescopes (SATs) consist of…
Anti-reflection coating with mullite and Duroid for large-diameter cryogenic sapphire and alumina optics
Kana Sakaguri, Masaya Hasegawa, Yuki Sakurai +10
We developed a broadband two-layer anti-reflection (AR) coating for use on a sapphire half-wave plate (HWP) and an alumina infrared (IR) filter for the cosmic microwave background…
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…
