SPTpol will consist of an 850 element polarization sensitive bolometric camera deployed to
the South Pole Telescope in late 2011. This camera is optimized for measurement of the
polarization of the cosmic microwave background with arcminute resolution. These
measurements will be used to constrain neutrino masses and to constrain the amplitude of
gravitational waves from inflation. The camera includes two detector architectures that
observe in two different frequency bands. At 150 GHz, SPTpol will use 650 feedhorn …
