SPT-3G detector pixels, Each pixel measures X and Y polarization at three different frequencies -- 95, 150, and 220 GHz - using six superconducting bolometers. The SPT-3G focal plane will be deployed during the 2016-17 Austral Summer and contain a total of 16,400 detectors.
Goal of the CMB Polarization hubThe goal of the CMB Polarization Hub is to coordinate and synthesize results from a number of experiments searching for B-mode polarization in order to minimize systematic errors due to backgrounds and maximize signal. With these combined results in hand, the probability of detection is maximized or the very strongest possible limits on inflationary gravitational waves will be established.

KICP researchers are working with the larger community to build the science and technology case for a Stage 4 CMB polarization experiment that will probe inflation with unprecedented sensitivity.
