Geometry Modernization of a Dipole Magnet for the SIS 300

Some technological and design peculiar properties have been discovered during working out design drawings and tooling for production of a short dipole model, which is being developed for synchrotron SIS 300, the FAIR project, GSI. These peculiarities should be taken into consideration during development of a full-scale prototype of the dipole. These features are related to both 2D and 3D geometries. This article presents some improvements that allow enhancing magnetic and mechanical characteristics, simplify processing complexity, and increase reliability and efficiency of the new design. Specifically, the field quality in the cross section is ameliorated. The length of the end parts is shortened, which gives larger effective length of the dipole.
