摘要：

An 80 mm long polarizing S-bender with a large cross-section of 30 x 100 mm(2) 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. (c) 2012 Elsevier B.V. All rights reserved.
