The soft X‐ray beamline BL23SU at SPring‐8 has undergone an upgrade with a twin‐helical undulator of in‐vacuum type to enhance the experimental capabilities of the endstations. The new light source with a fast helicity‐switching operation allows not only the data throughput but also the sensitivity in X‐ray magnetic circular dichroism (XMCD) to be improved. The operational performance and potential are described by presenting XMCD results of paramagnetic β‐US 2 measured with a 10 T superconducting magnet.
