The crystal on the diffractometer
The crystal on the diffractometer. The crystal sits at the end of the thin metal rod which is attached to the phi axis (from right to the middle of the image). The X-ray beam comes from the left side. The cryostream (which keeps the crystal cold) is seen in the upper left part of the image. On the right side you see the beam stop (prevents that the main beam hits the detector) and part of the detector (in white).
Xray setup II
A view onto the setup from the other side: The beam comes from the right, the detector is to the left, the phi axis (around which the crystal is rotated) comes from the front side and the cryo-stream is seen at the back side.
flight through virtual worlds
Much later: The structure is determined and the "flight through virtual worlds" can begin. Norbert Sträter (with stereo glasses) and Wolfram Saenger.
