Abstract

A 13-T superconducting magnet for neutron scattering experiments was being developed at the High Magnetic Field Laboratory, Chinese Academy of Sciences, which will provide a high magnetic field environment to research condensed matter physics. It is made up of 6 Nb3Sn coils and 8 NbTi coils to provide a 13-T central magnetic field with 0.5% field inhomogeneity in the sample region of Ø10 mm×10 mm cylinder. Due to the horizontal opening angle of 320° and the vertical opening angle of ±8°, there is a very limited space for the support structure, which is expected to withstand an electromagnetic force of approximately 200 tons; as a result, the design of the support structure is crucial in order to avoid any harmful plastic deformation. In this paper, the electromagnetic solution, structure design, and mechanical analysis are mainly presented.
