Production, quality assurance, documentation, cleaning, packing and shipping of 182 UHV vacuum chambers for the HESR vacuum system.

The synchrotron HESR (High Energy Storage Ring) will be operated within the FAIR Project (Facility for Antiproton and Ion Research). FAIR is being constructed at the GSI site in Darmstadt, Germany, and is a modern state-of-the-art particle accelerator facility for fundamental and applied research where international collaborations of scientists can conduct their experiments. This facility is being financed in international collaboration with presently 16 partner states. The company FAIR-GmbH has been founded in 2010 to take this task. The Research Center Juelich (Forschungszentrum Juelich, FZJ) planned the HESR and was contracted by FAIR GmbH to contribute the HESR to the FAIR facility.

In close collaboration with the colleagues at GSI, FZJ covers administrative and technical tasks, especially for the work package 'vacuum'. This acquisition deals with vacuum chambers designed for interconnecting the beam tubes and vacuum pumps, vacuum gauges, valves, or diagnostic instruments etc. All this UHV equipment will be operated in slowly varying magnetic fields up to a maximum strength of 1.7 T.
