“…The planned new $56 mm twin aperture dipole structure basically follows the present CERN's coil design [2], and the symmetric, separate collar feature is maintained [5]. The iron yoke is now horizontally split with a outer radius of 280 mm for the twin aperture dipole model magnet (MTA56KEK), while for single dipole model magnet (MSA56KEK) the iron yoke outer radius is 260 mm.…”

A new dipole model magnet design has been made with an aperture of 56 mm according to re-optimization of the accelerator design for the Large Hadron Collider GHC) to be built at CERN. A feature of "symmetriclseparate collar configuration'' in the new design proposed by KEK has been evaluated in terms of field quality and mechanical stability according to the process of the magnet fabrication, cool-down and excitations. The analysis has been carried out by using the finite element analysis code ANSYS, in linkage of field analysis with structural analysis. Effect of the deformation, due to electromagnetic force, on the field quality has been also investigated. Results of the analysis will be presented.
