A top view of the monochromator concept for hard X-ray ID beamlines at SLS 2.0. The concept foresees a modular building block that can accommodate one or two independent monochromators. Alternatively, one monochromator can be omitted, or integrated in the design later. The monochromators will have a maximum beam offset of 6 mm. As the first optical surface is placed within the direct undulator beam, the monochromators will be cryocooled. Two tungsten beam stoppers prevent bremsstrahlung from leaking into the experimental hutch and guarantee radiation safety. |
