3D numerical model of electromagnetic quadrupoles for the Grenoble European Synchrotron

摘要

The magnetic flux density B (B/sub x/ approximately=0, B/sub y/, B/sub z/ approximately=0) produced by the quadrupole magnets of the future Grenoble European Synchrotron is computed. This value is needed to obtain the focusing force acting on the electrons. The finite-element software package FLUX3D is used to compute the flux density B and other useful parameters. A second-order tetrahedral mesh and a reduced scalar potential formulation have been chosen to solve this problem, taking into account the inducing coils, with accurate results in nonferromagnetic materials.
