Broadband, millimeter-wave anti-reflective structures on sapphire ablated with femto-second laser
R. Takaku, S. Hanany, H. Imada +13
We designed, fabricated, and measured anti-reflection coating (ARC) on sapphire that has 116% fractional bandwidth and transmission of at least 97% in the millimeter wave band. The…
Optical Design of PICO, a Concept for a Space Mission to Probe Inflation and Cosmic Origins
Karl Young, Marcelo Alvarez, Nicholas Battaglia +28
The Probe of Inflation and Cosmic Origins (PICO) is a probe-class mission concept currently under study by NASA. PICO will probe the physics of the Big Bang and the energy scale of…
PICO - the probe of inflation and cosmic origins
Brian Sutin, Marcelo Alvarez, Nicholas Battaglia +31
The Probe of Inflation and Cosmic Origins (PICO) is a NASA-funded study of a Probe-class mission concept. The top-level science objectives are to probe the physics of the Big Bang…
The EBEX Balloon Borne Experiment - Detectors and Readout
The EBEX Collaboration, Maximilian Abitbol, Asad M. Aboobaker +37
EBEX was a long-duration balloon-borne experiment to measure the polarization of the cosmic microwave background. The experiment had three frequency bands centered at 150, 250, and…
Developments of highly-multiplexed, multi-chroic pixels for Balloon-Borne Platforms
François Aubin, Shaul Hanany, Bradley R. Johnson +4
We present our work to develop and characterize low thermal conductance bolometers that are part of sinuous antenna multi-chroic pixels (SAMP). We use longer, thinner and meandered…
CMB-S4 Technology Book, First Edition
Maximilian H. Abitbol, Zeeshan Ahmed, Darcy Barron +58
CMB-S4 is a proposed experiment to map the polarization of the Cosmic Microwave Background (CMB) to nearly the cosmic variance limit for angular scales that are accessible from the…
