Design, assembly, and initial test results of a cryostat for holographic characterization of microwave telescopes
Jon E. Gudmundsson, Miranda Eiben, Thomas J. L. J. Gascard +1
We describe the design, fabrication, assembly, and room-temperature vacuum qualification of a 1.4-m long cylindrical cryostat developed for holographic testing of cryogenic microwa…
Millimeter and sub-millimeter characterization of polymers used for infrared filters in high-sensitivity cryogenic microwave telescopes
Miranda Eiben, Rustam Balafendiev, Thomas Gascard +1
Vacuum windows and infrared filters are important transmissive optical components in millimeter receivers, as they hold out the atmosphere and reduce radiative loading on cold stag…
picoMUX: microcontroller based time-domain multiplexing readout for kilopixel TES arrays
Simon Tartakovsky, Alexandre E. Adler, Jason E. Austermann +23
Advances in cryogenic SQUID-based time-domain multiplexing (TDM) have outpaced their warm readout electronics. Next generation CMB telescopes are baselining kilopixel TES arrays wi…
Sub-Kelvin Cryogenics for a Super-Pressure Balloon-Borne CMB Polarimeter: Taurus
Jared L. May, Alexandre E. Adler, Jason E. Austermann +23
Taurus is a balloon-borne cosmic microwave background (CMB) experiment designed to operate more than 10,000 transition-edge sensor bolometers at a base temperature near 100 mK duri…
Optimizing broadband microwave absorbers for applications in the 70-200 GHz range
Gaganpreet Singh, Rustam Balafendiev, Mahesh Singh Bist +4
We present results of an extensive suite of numerical simulations that probe square-tiled microwave absorber performance as a function of material properties, frequency, geometry,…
Vector beam mapping at millimeter wavelengths using a robot arm
Rustam Balafendiev, Thomas Gascard, Jon E. Gudmundsson
Many experimental efforts are striving to provide deep maps of the cosmic microwave background (CMB) to shed light on key questions in modern cosmology. The primary science goal fo…
Instrument Overview of Taurus: A Balloon-borne CMB and Dust Polarization Experiment
Jared L. May, Alexandre E. Adler, Jason E. Austermann +20
Taurus is a balloon-borne cosmic microwave background (CMB) experiment optimized to map the E-mode polarization and Galactic foregrounds at the largest angular scales ( …
Reflectance measurements of mm-wave absorbers using frequency-domain continuous wave THz spectroscopy
Gaganpreet Singh, Rustam Balafendiev, Zeshen Bao +4
Due to high dynamic range and ease of use, continuous wave terahertz spectroscopy is an increasingly popular method for optical characterization of components used in cosmic microw…
Thermal and mechanical study of a parametrised cryostat model for optical characterisation of upcoming CMB experiments
Thomas J. L. J. Gascard, Yi Wang, Jon E. Gudmundsson +6
Current and future experiments observing the cosmic microwave background require a detailed understanding of optical performance at cryogenic temperatures. Pre-deployment analysis…
Design and experimental investigation of a planar metamaterial Silicon based lenslet
Thomas Gascard, Giampaolo Pisano, Simon Doyle +9
The next generations of ground-based cosmic microwave background experiments will require polarisation sensitive, multichroic pixels of large focal planes comprising several thousa…
