The BRAIN experiment |
Abstract _ |
The BRAIN experiment is a bolometric interferometer devoted to measure the B-modes polarization of the Cosmic Microwave Background from Concordia station in Antarctica. We report the results obtained during the first campaign we carried out this austral summer at Dome-C. Using a pathfinder experiment, we demonstrated that a cryocooler based cryogenic system can work in such environmental conditions. We also carried out preliminary observations of the atmospheric emission at 145GHz from Dome-C, and during the next campaign we'll extend the measurements to all the Stokes parameters I, Q, U, V all over the winter. |
