"The QUaD CMB Polarization Experiment"

Detailed measurements of polarization of the Cosmic Microwave Background (CMB) are the goals of the next generation of CMB experiments. In particular these experiments hope to distinguish curl modes of polarization, which contain information about gravity waves in the early universe, from the dominant curl-free modes that trace density perturbations at the surface of last scattering. I will describe the design and status of the QUaD polarization experiment which will be fielded at the South Pole in late 2004, and which could potentially detect curl modes of polarization.
