Key contracts signed for the CR storage ring at the FAIR accelerator facility
The preparations for the development and construction of the Collector Ring (CR) at the future FAIR accelerator center are making decisive progress. To this end, a delegation of officials from FAIR/GSI and the Budker Institute for Nuclear Physics (BINP) signed several contracts during a visit to Novosibirsk, Russia. The delegation included the technical managing director of FAIR and GSI, Jörg Blaurock, and the overall head of the FAIR project, Dr. Jürgen Henschel.
At the FAIR facility, the CR will store particle beams from a variety of sources and cool the stored particles. It will be possible to use the cooled particle beams to conduct additional experiments directly in the CR or in the linked High-Energy Storage Ring (HESR). A large part of the CR is being developed under the direction of the Budker Institute as Russia’s contribution to FAIR. The Budker Institute also bears the main responsibility for the Collector Ring.
BINP is supplying all of the magnets, for example, as well as the vacuum and energy supply systems. One of the recently signed contracts governs the provision of 26 dipole magnets, each of which weighs almost 50 tons. “They will be among the biggest magnets that we’ll be using at FAIR,” explains Dr. Jürgen Henschel, who manages the overall project. “The contract we’ve just concluded with the Budker Institute is the key contract for the Collector Ring.”
Another development contract that was also signed at the recent meeting in Novosibirsk stipulates how topics related to the technologically demanding Collector Ring will be addressed at the same time as the facility is built.
The key contracts for all of the rings at FAIR — from the 1.1 kilometer long SIS100 ring accelerator to the High-Energy Storage Ring (HESR) — have now been signed.
