Planar Silicon Metamaterial Lenslet Arrays for Millimeter-wavelength Imaging
Christopher M. McKenney, Jason E. Austermann, James A. Beall +7
Large imaging arrays of detectors at millimeter and submillimeter wavelengths have applications that include measurements of the faint polarization signal in the Cosmic Microwave B…
Anomalous Frequency Noise from the Megahertz Channelizing Resonators in Frequency-Division Multiplexed Transition Edge Sensor Readout
John Groh, Kam Arnold, Jessica Avva +11
Superconducting lithographed resonators have a broad range of current and potential applications in the multiplexed readout of cryogenic detectors. Here, we focus on LC bandpass fi…
The Simons Observatory: gain, bandpass and polarization-angle calibration requirements for B-mode searches
Maximilian H. Abitbol, David Alonso, Sara M. Simon +45
We quantify the calibration requirements for systematic uncertainties for next-generation ground-based observatories targeting the large-angle -mode polarization of the Cosmic M…
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…
CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
S4 Collaboration, Kevork Abazajian, Graeme E. Addison +233
CMB-S4---the next-generation ground-based cosmic microwave background (CMB) experiment---is set to significantly advance the sensitivity of CMB measurements and enhance our underst…
Characterization of Transition Edge Sensors for the Simons Observatory
Jason R. Stevens, Nicholas F. Cothard, Eve M. Vavagiakis +31
The Simons Observatory is building both large (6 m) and small (0.5 m) aperture telescopes in the Atacama desert in Chile to observe the cosmic microwave background (CMB) radiation…
Updated design of the CMB polarization experiment satellite LiteBIRD
H. Sugai, P. A. R. Ade, Y. Akiba +216
Recent developments of transition-edge sensors (TESs), based on extensive experience in ground-based experiments, have been making the sensor techniques mature enough for their app…
