Setup of beamline BL 14.1 (BESSY II, Berlin) (U. Mueller et al., in preparation). (a) Global view of the experimental hutch. Clearly discernible are the CCD detector (left), the MD2 diffractometer with the mounted cryo-system (center) and the robot arm of the CATS sample changer (right) (Irelec, Saint-Martin-d'Hères, France). The UV laser source (indicated by a blue arrow) is mounted on a movable arm. The current view is in the resting state. (b) Close-up view of the sample position with the UV laser moved down into the experiment state. The two screws (indicated by the light-blue arrows) on the xy table (black) are used for aligning the UV laser onto the crystalline sample. (c) Further close-up view of the sample environment. The crystal is fluorescing in the UV beam. |
