Under the direction of Prof. Dr. Tim Salditt, the scientist set-up a central lab for short-pulse X-ray analysis, which was also equipped with a so-called diffraction (XRD) chamber, where a Princeton-CCD-camera with a in-vacuum water-cooling system is used. All components should be highly flexible in order to make a quick set-up, removal and altering possible. The Göttingen expert was in demand of full-vacuum fit, highly compact self-sealing couplings in the nominal bore of DN 4 to 6 for maximum pressure of 8 bar. In addition, Dr. Mai put emphasis on removing the camera in a „dry“ way, without any leakage of cooling water.
„I remembered Walther because during my doctoral studies I used their couplings for helium lines, and I never had a problem with any kind of leakage.” Finally, it was decided to use the specially adapted CT-005 clean-break coupling of Walther-Präzision to be able to remove the camera quickly from the cooling circuit of the installation.
Walther-Präzision installed the couplings and carried out the leakage test in a connected state. The required tightness (10-8 mbar• l/s) was excelled with a peak value of only (10-10 mbar• l/s). This result was well received in Göttingen: The self-sealing couplings have now even replaced the normal hose connections at the water-cooled turbo pump that is more mobile now thanks to CT-005.
