Regular 15 minutes Oral Presentation A5 - Particle Detector Magnets Wed-Af-Or25

CERN, in collaboration with its partner laboratories, is presently undertaking a design study of the Future Circular Collider including electron-positron and proton-proton collider variants. A 100 km long circular tunnel is foreseen featuring some 400 m below surface a few caverns for housing general purpose detectors probing e-e+ and p-p collisions. The design effort shall lead to a conceptual design report by the end of 2018 necessary for preparing the next step eventually leading to a new collision machine by medio 2045. The FCC effort comprises options for new detector magnets presently being explored. The design effort, in place since 2014, will show new baseline designs for both the ee+ and pp detector magnet systems. For the pp collisions detector the 14 GJ magnet system features a 10 m diameter, 19 m long, 4 T central solenoid in combination with two 5 m free bore, 3.5 m long 4 T solenoids covering the low angle forward directions. For the ee+ detector the baseline comprises a more classical 0.74 GJ solenoid providing 2 T in a 6.6 m free bore and 8 m length. The peak magnetic field in the coil windings is 4.6 T and 2.5 T, respectively, comfortably within reach of NbTi technology. The design drivers for the magnets set by physics requirements are highlighted and various options for these records breaking magnets are presented.
