With the FAIR project (Facility for Antiproton and Ion Research), a state-of-the-art particle accelerator and experimental facility for basic and applied research is being realized in cooperation with 16 partner countrie…
s at the GSI Helmholtzzentrum für Schwerionenforschung GmbH (GSI) site in Darmstadt. The fast-closing valves to be procured here are used to react quickly and reliably in the event of an air leak. A loss of a UHV or XHV environment due to air ingress, especially with large volumes such as accelerato
rs or storage rings, can lead to considerable problems in terms of contamination, damage to system components and the effort required to restore the required vacuum level.
