Abstract
Spider is a balloon-borne array of six telescopes that will observe the Cosmic Microwave Background. The 2400 antenna-coupled bolometers in the instrument will make a polarization map of the CMB with ~degree resolution at 150 GHz and 95 GHz. Polarization modulation is achieved via a cryogenic sapphire half-wave plate (HWP) skyward of the primary optic. In this thesis, the design, construction, and lab testing of the HWP system are discussed. The polarization modulation of these optical stacks is modeled using a physical optics calculation and Mueller matrices. Performance tests in both the lab and integrated in the flight cryostat show consistency with the model.
