Development of the characterization methods without electrothermal feedback for TES bolometers for CMB measurements
Yume Nishinomiya, Akito Kusaka, Kenji Kiuchi +6
Superconducting Transition-Edge Sensor (TES) bolometers are used for cosmic microwave background (CMB) observations. We used a testbed to evaluate the thermal performance of TES bo…

The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
The Simons Observatory Large Aperture Telescope Receiver
Ningfeng Zhu, Tanay Bhandarkar, Gabriele Coppi +68
The Simons Observatory (SO) Large Aperture Telescope Receiver (LATR) will be coupled to the Large Aperture Telescope located at an elevation of 5,200 m on Cerro Toco in Chile. The…
Commissioning the CMB polarization telescope GroundBIRD with the full set of detectors
Miku Tsujii, Jochem J. A. Baselmans, Jihoon Choi +39
GroundBIRD is a ground-based cosmic microwave background (CMB) experiment for observing the polarization pattern imprinted on large angular scales ( ) from the Teide Obse…
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: Metamaterial Microwave Absorber (MMA) and its Cryogenic Applications
Zhilei Xu, Grace E. Chesmore, Shunsuke Adachi +26
Controlling stray light at millimeter wavelengths requires special optical design and selection of absorptive materials that should be compatible with cryogenic operating environme…
