The polarizer uses spin-selective reflection of neutrons by interfaces coated with polarizing super-mirrors. The polarizer is built entirely in-house for the PF1B cold neutron beam facility at the Institut Max von Laue - Paul Langevin (ILL). It has been installed in the PF1B casemate and tested at real conditions. The average transmission for the \"good\" spin component is measured to be >30 %. The polar","authors_text":"A.
