摘要

Polarisation modulators are necessary for present and next generations of CMB polarisation experiments. Because of thevery faint B-mode signal expected, these instruments have not only to be extremely sensitive but also to have low andwell-characterised systematic effects.The beam RF characterisation in the W-band (75-110 GHz) of two polarimeter pixels using the same corrugated horn hasbeen performed using two different modulators: a waveguide rotator modulator and a quasi-optical half-wave plate. Coandcross-polarisation beam measurements are presented together with the systematic effects introduced by bothmodulators.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
