Problems solved by technology
In addition to the extra work in the coil manufacturing process, the stiffening elements inside the proposed layered conductor coil assembly would deteriorate the geometrical accuracy of the magnet coil windings, resulting in an inhomogeneous magnetic field
Also, winding the cylindrical waist layers after each cylindrical conductor layer requires cutting and splicing the conductors, which increases the risk of imperfections in the superconducting path throughout the layered conductor coil assembly
As proposed in [12], the risk of quenching in a superconducting magnet due to the fracture of the rigid filling material under the magnetic force acting on the coil assembly of a cylindrical magnet can be mitigated, but not completely avoided, by optimizing the filling material
