Q/U Imaging ExperimenT (QUIET)
QUIET was a pathfinder Cosmic Microwave Background (CMB) B-mode polarization experiment (left figure) located in the Atacama desert in Chile, designed to demonstrate the applicability of Monolithic Microwave Integrated Circuits (MMICs; right figure) for deep CMB polarization observations. Observations were made between 2008 and 2010 at two different frequencies, 43 and 95 GHz, each covering a total of ~2400 square degrees divided over four low-foreground and two Galactic fields. Science highlights from these measurements include:
