title: Transmission multilayer polarizers for use in the 55-90 eV region.
abstract: Free-standing Al/YB(6) and Mo/Si transmission multilayer polarizers have been developed for use in the photon energy regions 55-72 eV and 72-90 eV, respectively, to improve the degree of polarization of synchrotron radiation light from beamline monochromators. The polarizance (polarizing ability) and transmittance of the Al/YB(6) multilayer for unpolarized light at 64 eV were 77% and 3.4%, respectively, and the polarizance and transmittance of the Mo/Si multilayer at 80 eV were 79% and 2.2%, respectively. By using the Mo/Si polarizer, the degree of polarization of the monochromated light at BL8B1 of UVSOR was increased from 95 to 99% in the 78-84 eV region.
