Design of the New Wideband Vivaldi Feed for the HERA Radio-Telescope Phase II
Nicolas Fagnoni, Eloy de Lera Acedo, Nick Drought +5
This paper presents the design of a new dual-polarised Vivaldi feed for the Hydrogen Epoch of Reionization Array (HERA) radio-telescope. This wideband feed has been developed to re…
A cryogenic rotation stage with a large clear aperture for the half-wave plates in the Spider instrument
Sean Bryan, Peter Ade, Mandana Amiri +47
We describe the cryogenic half-wave plate rotation mechanisms built for and used in Spider, a polarization-sensitive balloon-borne telescope array that observed the Cosmic Microwav…
Modeling and characterization of the SPIDER half-wave plate
Sean A. Bryan, Peter A. R. Ade, Mandana Amiri +42
Spider is a balloon-borne array of six telescopes that will observe the Cosmic Microwave Background. The 2624 antenna-coupled bolometers in the instrument will make a polarization…
