Design of an apparatus for polarization measurement in soft X-ray region

Imazono, Takashi; Suzuki, Yoji; Sano, Kazuo*; Koike, Masato

To meet the needs we have been developing an apparatus to evaluate polarization abilities of multilayer- and crystal-types polarizing elements and determine the polarization state of light in 1 keV region. The 8-axis goniometer called the polarization analysis-unit is equipped in this apparatus and consists of a phase shifter-unit and an analyzer-unit. All axes can be driven with HV compatible stepping motors. Both reflection- and transmission-types samples are available on P and A. Therefore, this apparatus makes it possible to carry out not only conventional reflection and transmission measurements but also four scanning modes which are double- reflections and transmissions, and transmission-reflection and vice versa.
