Abstract:
An 80 mm long polarizing S-bender with a large cross-section of 30100 mm2 for the instrument MIRA at the FRM II has been simulated, built and tested. The results of the experiment show for the wavelength of 4.4 ˚A a homogenous polarization of more than 98% across the bender cross-section and a high transmission of above 65% of the spin up component of the neutron beam. The bender design has the advantage of delivering the polarized beam in the direction of the incoming beam.
