18.09.2018 | Collector Ring: Contract with Budker Institute has been signed
The course for development and construction of the Collector Ring (CR), an important part of the future FAIR accelerator center, has been completely set. During the visit of a delegation of representatives of the Budker Institute for Nuclear Physics (BINP) to the FAIR and GSI campus, the contract for the remaining part of the CR was signed together with the management of FAIR and GSI. Prior to this, two contracts concerning the responsibility for the CR project realization and the dipole magnets construction for the CR had already been concluded.
The CR is designed for fast precooling of hot secondary ions coming from the antiproton separator and the Superconducting Fragment Separator (Super-FRS). The fast cooling will be done by means of the RF debuncher and stochastic cooling systems, which are developed by GSI. The CR is going to be used for mass measurements of short-lived secondary rare isotope beams from the Super-FRS in a special CR optical mode as well.
A large part of the CR is being developed under the direction of the Budker Institute as a Russian in-kind contribution to FAIR. The Budker Institute also bears the main responsibility for the Collector Ring. The signed contracts provides that BINP manufactures dipole, quadrupole and sextupole magnets, a vacuum system, power supplies for all magnets, beam diagnostic components and injection/extraction system. The most challenging components are 26 dipole magnets weighing almost 60 tons each. The BINP is responsible for assembly and commissioning of all CR components at FAIR site.
With the contract now signed, all decisive prerequisites for the technological demanding Collector Ring are in place. (BP)
