Description
At the site of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt (Germany) the international accelerator Facility for Antiproton and Ion Research (FAIR) is currently under construction. FAIR is going to be one of the largest research facilities worldwide. In its accelerator chain there will be two large machines with superconducting magnets, the heavy-ion synchrotron SIS100 and the isotope separator SuperFRS, with a total helium cooling inventory of more than 8 tons, as well as several experiments and small users of liquid helium. Altogether 108 dipole magnets for the SIS100 have to be tested in advance in the recently commissioned Series Test Facility (STF) at GSI.
The liquid helium supply for FAIR will be provided by one large refrigerator with a capacity of 25 kW (4.3 K equivalent), a cool-down and warm-up unit (CWU) with a capacity of 80 kW (at 80 K), and by several small refrigerators and liquefiers located over the FAIR campus, combined with approximately 1.6 km of transfer lines.
In this presentation the progress of the cryogenic infrastructure at FAIR will be presented with a focus on the magnet testing, the distribution systems, and the large cryo plants.
