General components

The first component in the first experimental hutch EH1 is a FMB Oxford beam positioning monitor (BPM). A water cooled diamond window (5 mm OD, 60 micron thickness) is connected downstream to the BPM. This device combination sits on a granite post and can be aligned to the beam using two Huber stages (vertical and horizontal).  The travel ranges allow to shift between 'pink' and 'monochromatic' beam options.  It is possible to stabilize the beam position at the BPM using vertical and/or horizontal feedback programs.

The next object in EH1 is a 2.7m long optical table. This 5-axis table (Q-SYS) carries several shared components for the beamline.  Situated on a granite spacer are a pink beam capable slit system with a nominal opening of 10x 10mm<sup>2</sup> as well as a fast shutter system, an absorber system and a first monitor unit.

The fast shutter unit houses two separate shutter systems:  A water-cooled, piezo driven shutter system with ~1ms response time and a slower (~30ms) actuator driven shutter.  The fast system has a small opening of ~0.7 mm and can be moved out of the beam by a linear translation.
The absorber consists of two linear translations.  Each translations is equipped to hold 9 different absorbers. Currently the center position is left empty on both stages and two different materials are mounted on the different sides.  One half holds Silver absorber for X-ray photon energies above 12 keV and the other half holds both sided polished thin Silicon crystals for lower X-ray energies.
Finally, the monitor unit is based on scattering of a thin Kapton foil under 45° in combination with a Cyberstar scintillator detector.
