The effect of a scanning flat fold mirror on a CMB B-mode experiment
arXiv:1105.3409 · doi:10.1063/1.3598342
Abstract
We investigate the possibility of using a flat-fold beam steering mirror for a CMB B-mode experiment. An aluminium flat-fold mirror is found to add 0.075% polarization, which varies in a scan synchronous way. Time-domain simulations of a realistic scanning pattern are performed, and the effect on the power-spectrum illustrated and a possible method of correction applied.
