Ideal coil shape for combined function superconducting magnets

Abstract

Coil shapes for generating the perfect field in superconducting dipoles, quadrupoles and sextupoles are known. However, for combined function superconducting magnets coil shapes are not available in the literature. Here we provide the coil shapes which can generate mixed dipole–quadrupole and dipole–sextupole fields.

Magnetic levitation in two-dimensional geometry with translational invariance

“…30,31 In addition, the development of large superconducting coils has been made necessary by that of particle accelerators such as relativistic heavy ion collider ͑RHIC͒ or large hadron collider ͑LHC͒. [32][33][34] The large accelerators need of multipolar windings-dipole, quadrupole, etc.-to guide the beam in cylindrical geometry, [35][36][37] i.e., with translational invariance. Recently, theoretical studies on magnetic levitation of deuterium or water have been published.…”
