Design
The X-ray scanner system is made up of a vacuum chamber on a support frame, which connects to the beamline through connecting bellows. In the picture on the right the vacuum chamber is shown transparent, outlined in blue. The scanning stage is mounted inside the vacuum chamber with the mask and substrate assembly and the rotation and tilt module.
The support frame carries the whole load of the scanner system and is highly mechanically stable. Manual screw jacks allow a vertical movement range of ±25mm to adjust to changes in beam height.
