The optics hutch (OH) is 8.7 m long and 3.2 m wide. The x-ray beam enters the hutch from a wall located at 23 m (??) from the source. Along the beam we successively find a prepumping vessel, a valve (RV0), a beam splitter, a pair of primary slits, a set of attenuators, chopper, white beam viewer, a standard double-crystal monochromator (DCM, 6 keV- 60 keV) and a double-multilayer monochromator (DMM, 6 keV- 30 keV). When inserted into the beam both monochromators are deflecting the beam vertically. Notice that, with the recent accelerator upgrade, the maximum beam collection in the horizontal direction if of 1.6 mrad.

A shutter controls the introduction of the beam into the following hutch (EH1) physically separated from OH by a lead wall. Free space is available in-between the DCM and DMM stations to accommodate future optical components.

You can find here information about the Beryllium Windows being used to seal off the vacuum areas of the beamline from the non-vacuum areas.
