A 16 Tesla Nb/sub 3/Sn dual dipole was developed in this article to extend the available field strength for future hadron colliders by incorporating several novel features.Abstract:
A 16 Tesla Nb/sub 3/Sn block-coil dual dipole is being developed to extend the available field strength for future hadron colliders. The design incorporates several novel features. Current programming of 3 independent coil elements is used to control all multipoles over a 20:1 dynamic range of dipole field. Stress management, comprising a lattice of ribs and plates integrated into the coil structure, is used to distribute preload and Lorentz forces so that the stress in the coil never exceeds 100 MPa. Distributed cooling, utilizing spring elements in each coil block, intercepts heat generated by synchrotron radiation and beam losses. Rectangular pancake coil geometry accommodates simple fabrication and direct preload in the direction of Lorentz forces. The bore diameter can be optimized for collider requirements (2.5 cm for 50 TeV/beam vs, 5 cm for 8 TeV/beam), so that a 16 Tesla block-coil dipole for 50 TeV/beam requires the same amount of superconductor/TeV as the 8.5 Tesla LHC dipole for 8 TeV/beam. A first model of the dipole is currently being built.read more
