FAIR and JINR conclude contract on the construction of magnets for particle accelerator
After their completion the magnets will undergo extensive testing in Dubna prior to their deployment at FAIR.
The superconducting magnets were designed by GSI Helmholtzzentrum für Schwerionenforschung and are based on joint development work with JINR over a period of many years. They are the central components in the ring accelerator SIS 100 and keep the particles, which travel close to the speed of light, in their orbit.
In the development of the superconducting magnets it has been possible to unite two technologies for the first time.
The magnets are fitted with superconducting cables, which allow for a very fast change in the magnetic field. At the same time the vacuum chambers into which the particle beams are fed are cooled to almost minus 273 degrees Celsius. For only so can the maximum magnetic field be created within half a second and at the same time the necessary vacuum, of one billionth of the ambient pressure, be attained. Under these conditions it is possible to accelerate very heavy atomic nuclei virtually to the speed of light.
