Abstract

Bicep is a ground-based millimeter-wave bolometric array designed to target the primordial gravity wave signatureon the B-mode polarization of the cosmic microwave background (CMB) at degree angular scales. Currentlyin its third year of operation at the South Pole, Bicep is measuring the CMB polarization with unprecedentedsensitivity at 100 and 150 GHz in the cleanest available 2% of the sky, as well as deriving independent constraintson the diffuse polarized foregrounds with select observations on and off the Galactic plane. Instrumentcalibrations are discussed in the context of rigorous control of systematic errors, and the performance during thefirst two years of the experiment is reviewed.

Abstract

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 map of the CMB with approximately one-half degree resolution at 145 GHz. Polarization modulation is achieved via a cryogenic sapphire half-wave plate (HWP) skyward of the primary optic. We have measured millimeter-wave transmission spectra of the sapphire at room and cryogenic temperatures. The spectra are consistent with our physical optics model, and the data gives excellent measurements of the indices of A-cut sapphire. We have also taken preliminary spectra of the integrated HWP, optical system, and detectors in the prototype Spider receiver. We calculate the variation in response of the HWP between observing the CMB and foreground spectra, and estimate that it should not limit the Spider constraints on inflation.
