BL-11A : Soft X-Ray Grazing Incidence Monochromator Station

The current BL-11A, BL-11B and BL-11D will be shut down at the end of FY2022 due to the construction of a multi-function R&D beamline. The activities of these beamlines will be continued at the new BL-12A (scheduled to start in late FY2023) and the existing beamlines. For more information, see Reconstruction of BL-11 and BL-12.
