Block-coil dipole for future hadron colliders

A first model dipole is being built for a block-coil dipole for future hadron colliders. The design incorporates stress management, in which Lorentz stress is intercepted between successive sections of the coil and bypassed through a support matrix. By controlling stress, the dipole should make it possible to utilize Nb/sub 3/Sn and BSCCO superconductors without strain degradation at high field. The first model dipole is being built using NbTi cable in order to evaluate fabrication techniques and stress management performance.
