QUBIC: a Fizeau interferometer targeting primordial B-modes
International audience QUBIC (Q and U Bolometric Interferometer for Cosmology) is a Fizeau interferometer sensi- tive to linear polarisation, to be deployed at the Antarctic Station of Dome C. This experiment in its nal conguration will be operated at 97, 150 and 220 GHz, and is intended to target C...
