A multiple-CCD X-ray detector and its basic characterization

This paper describes the design concept of a multiple-CCD X-ray detector as well as the initial performance test carried out with a conventional X-ray generator system.

Rotated-inclined focusing monochromator with simultaneous tuning of asymmetry factor and radius of curvature over a wide wavelength range

In order to achieve simultaneous tuning of the beam demagnification rate and the radius of curvature for focusing over a wide wavelength range, a new single-crystal focusing monochromator has been developed.

Polarization-modulation technique with diamond phase retarder to improve the accuracy of XMCD measurements

Polarization tunability and analysis for observing magnetic effects on BL39XU at SPring-8

High performance of polarization tunability and analysis of X-rays at SPring-8 is demonstrated by observing several magnetic effects. A diamond phase plate plays an essential role in regulating the polarization states.
