Abstract

A measurement system for circular dichroism (CD) of soft X-ray absorption has been developed using helicity switching of circularly polarized radiation by twin helical undulators at BL25SU of SPring-8. Difference of horizontal spot positions between the negative- and positive-helicity light at the sample position is within ±3μm. Measurement time for magnetic circular dichroism (MCD) of core absorption is shortened to less than 1/3 in comparison with an existing system of magnetic field switching, keeping the same data quality.
