Abstract

We have proposed an original Michelson type bolometric interferometer dedicated to CMB B mode observations in which a large format detector array is able to mounted on the focal plane since the diameter of the primary beam do not have to be smaller than the baseline length of the interferometer and is able to be taken as large as one want. This instrument is named as MuFTPol. The MuFTPol dramatically improves the sensitivity of the B mode experiments based on Michelson type bolometric interferometer otherwise the primary beam size could not be larger than 10cm in the CMB B mode experiment targetting the gravity wave origin B mode.
