Design of a novel simplified dodecapole field magnet
-
Abstract
Beam distribution with the regular and homogeneous form on spallation target or beam dump is an imperious demand for spallation neutron source (SNS), accelerator driven sub-critical system (ADS), and so on. Nowadays, adopting nonlinear antisymmetric high order field is very infusive for distribution transformation of beam. Here, a simplified dodecapole field magnet (SDFM), well focusing particles in beam halo to inner layer of beam halo or beam core, was introduced. Combining SDFM with antisymmetric sextupole, octupole or decapole magnet can theoretically get approximate uniformly distributed round beam with slightly larger size. The conceptual design, physics structural and its manufacturing method of SDFM was presented.
