Abstract

The Q/U Imaging Experiment (QUIET) is an experimental program to make very sensitive measurements of the Cosmic Background Radiation (CMB) polarization from the ground. A key component of this project is the ability to produce large numbers of detectors in order to achieve the required sensitivity. Using a breakthrough in mm-wave packaging at JPL, a polarimeter-on-a-chip has been developed which lends itself to the mass-production techniques used in the semiconductor industry. We describe the design, implementation and performance of these polarimeter modules for QUIET Phase I and briefly discuss the plans for further module development.

© 2010 SPIE. The seven U.S. QUIET Institutions are funded through an NSF Award (AST-0506648). Support also provided by AST-04-49809, DE-AC02CH11231, JSPS KAKENHI (A) 20244041, NSF PHY-0355328 and by the Strategic Alliance for Implementation of New Technologies (SAINT). Some work presented was performed on the Joint Fermilab – KICP Supercomputing Cluster, supported by grants from Fermilab, Kavil Institute for Cosmological Physics, and the University of Chicago. We are particularly grateful to Mary Soria (JPL), April Campbell (Wedgeway) and Heather Owen (JPL) for the assembly of the QUIET modules, and to the engineers who maintained and operated the telescope: J. Cortes, F. Munoz, and C. Verdugo.
