In order to reduce X-ray parasitic scattering with air and maximize the photon flux at the sample, an optimized beam conditioning optics has been designed and built in the end station, integrating previously used and new components in vacuum. The beam conditioning optics includes a fast shutter, a set of commercial guard slits and a diagnostic unit com-prising three filters and a four-quadrant transmissive photodiode. In addition, a set of refractive beryllium lenses allowsμfocusing of the beam. The lens system can be removed from the beam path remotely. Finally, an on axis sample viewing system, with a novel design based on an in-vacuum camera mirror and a mica window minimizes the beam path in air up to the sample. To facilitate the alignment of the elements with respect to the beam, all the subsystems are supported by a high-stability granite table with 4 degrees of freedom and sub-micron resolution.
