Some figures of merit about transfer line magnets(for LHC to FCC) Attilio Milanese 1 Jul. 2014
Dipoles between SPS and LHC at CERN • resistive, copper coils • water cooled • field 1.8 T • aperture 70 × 25 mm • pole width 120 mm • iron length 6.3 m • current 5270 A • power 54 kW each • 112 units in TI-2 (6.2 MW) • 236 units in TI-8 (13.1 MW) • built by BINP http://norma-db.web.cern.ch Attilio Milanese
Quads between SPS and LHC at CERN • resistive, copper coils • water cooled • gradient 53.5 T/m • aperture 32 mm diameter • iron length 1.4 m • current 530 A • power 8.5 kW each • 95 units in TI-2 (0.8 MW) • 82 units in TI-8 (0.7 MW) • built by BINP http://norma-db.web.cern.ch Attilio Milanese
Combined functions at J-PARC • superconducting, Nb-Ti • supercritical helium cooling • field 2.59 T • gradient 18.6 T/m • 173.4 mm inner diameter coil • magnetic length 3.3 m • current 7345 A • 28 magnets T.

Tevatron dipoles • superconducting, Nb-Ti • 4.2 K operation, warm iron • field 3.9 T • aperture 76 mm diameter • The Tevatronaccelerator, whose circumference is comparable to the total length of TI2 and TI8 beam lines, requires 24 kW of cryogenic power at 4.2 K thus requiring about 7.9 MW of electric power.
