Summary: | collaboration 2 Abstract. The characterisation of CMB polarisation is one of the next challenges in observational cosmology. This is especially true for the so-called B-modes that are at least 3 orders of magnitude lower than CMB temperature fluctuations. A precise measurement of the angular power spectrum of these B-modes will give important constraints on inflation parameters. We describe two complementary experiments, BRAIN and CLOVER, dedicated to CMB polarisation measurement. These experiments are proposed to be installed in Dome-C, Antarctica, to take advantage of the extreme dryness of the atmosphere and to allow long integration time. 1 |
