The SPring-8 BL23SU (JAEA Actinide Science beamline) has been upgraded by the replacement of the original APPLE-2 type undulator with a twin helical undulator using in-vacuum devices. Recently, polarization switching between beams of opposite helicity at 1 Hz has reached operational status. The test results clearly show that the new light source is very well suited for the measurement of precision X-ray absorption, magnetic circular dichroism, spectra, as well as element-specifc hysteresis loops.
