MAGNETIC FIELD DISTRIBUTION CONTROL METHOD, MAGNETIC FIELD GENERATOR, AND ACCELERATOR

摘要

PROBLEM TO BE SOLVED: To provide a magnet field distribution control method which can provide high accuracy in magnet field distribution at a low cost, a magnet field generator and an accelerator using the same.;SOLUTION: The magnetic generator is characterized in that an anisotropic intermediate magnetic pole having different permeabilities in one or more directions is arranged in a magnetic field. For example, a material having magnetic anisotropy or a combination of materials having different permeabilities is used as the anisotropic intermediate magnetic pole. For example, in an accelerator for controlling the orbit of a beam by the magnetic generator, the magnetic generator comprises a main magnetic pole around which a coil is wound and an anisotropic intermediate magnetic pole arranged in a region of magnetic distribution formed by the main magnetic pole and having different permeabilities in one or more directions.;COPYRIGHT: (C)2006,JPO&NCIPI
