First Prototype of a Super Conducting Dipole Magnet for the Super-FRS at FAIR

A paper introducing the fruitful visit of Prof. Horst Stoecker to IMP(Institute of Modern Physics),CAS and the status of the first super conducting prototype dipole magnet to be used for the planned Super-FRS facility at FAIR appeared in the GSI Kurier recently. See the paper in German and English below.

Erster Prototyp eines supraleitenden Dipolmagneten f r den Super-FRS an FAIR

Die FAIR China Group (FCG, bestehend aus den Instituten IMP Lanzhou, IPP Hefei und IEE Peking) hat den ersten supraleitenden Prototyp-Dipolmagneten fertig gestellt, der im geplanten Super-Fragment-Separator (Super-FRS) an FAIR eingesetzt werden soll. Der Magnet wurde bereits erfolgreich in Betrieb genommen und soll in den kommenden Monaten ausf hrlich getestet werden. Der Dipol wiegt fast 50 Tonnen, ist ber 2 Meter lang und erzeugt eine maximale Flussdichte von 1.6 Tesla in einer sehr gro en Apertur von 400 140 mm2 (im Vergleich: LHC Dipol 50 50 mm2). Insgesamt werden 24 Magnete dieser Art f r den Super-FRS ben tigt, um damit sehr seltene und bisher unbekannte Atomkerne zu erzeugen und zu erforschen. Das Foto zeigt den Wissenschaftlichen Gesch ftsf hrer Horst St cker am Magnet im IMP (Institute of Modern Physics) in Lanzhou.

First prototype of a super conducting dipole magnet for the Super-FRS at FAIR

The FAIR China Group (FCG consisting of the institutes IMP Lanzhou, IPP Hefei, and IEE Beijing) accomplished the first super conducting prototype dipole magnet to be used for the planned Super-FRS facility at FAIR. The magnet was put successfully into operation and will be tested in detail in the forthcoming months. The dipole weights about 50 tons, has a length of more than two meters and reaches a magnetic flux density of 1.6 Tesla in the very large aperture of 400 140 mm2 (for comparison: LHC dipole 50 50 mm2). In total 24 magnets of this kind are needed for the Super-FRS which will be used to produce and investigate rare isotopes and to discover new neutron rich nuclides. The picture shows the scientific director of GSI Horst St cker with the magnet at IMP in Lanzhou.
