The Q/U Imaging Experiment (QUIET) is a ground-based CMB polarization experiment based on correlation polarimertry using high electron mobility transistor (HEMT) amplifiers. QUIET is designed to measure the CMB polarization on angular scales where the spectrum from inflationary gravity waves is predicted to be maximal. QUIET operates at two frequency bands centered at 40 GHz and 90 GHz. The 40 GHz receiver was deployed in 2008 at 5100m altitude in the Atacama Desert, Chile, and has finished data collection, logging over 3500 hours on the sky and covering 1200 square degrees. The 90 GHz receiver was deployed on the same telescope and started taking data in July 2009. I will present an instrument overview and the status of data analysis from the 40 GHz season.
QUIET is supported by NSF grants AST-04-49809 and AST-05-06648.
