High-Field Superconducting Magnets for Particle Accelerators
Particle Physics requires higher and higher energy accelerators-colliders to explore the fundamental components of matter. For electron-positron accelerators, circular machines, which make use of low bending magnetic field to limit synchrotron radiation, have probably reached their maximum size with LEP and the trend for the future is towards linear facilities. For high energy hadron accelerators/colliders, superconducting magnets have been adopted in order to save electrical energy and reduce machine size, and the quest for cost efficiency pushes towards higher field. The 9 to 10 tesla range has already been attained in short dipole magnets.
The large proton accelerators/colliders presently under construction, approved or planned represent the largest scale application of superconductivity and require massive production in industry of advanced technology conductors, magnets and cryogenic equipment.
A review is given of the magnets for these projects and of the future trends supported by R. &D. programs.
