Thermal and magnetic design of a dipolar superferric magnet for high uniformity magnetic field

This paper reports a mathematical model and numerical, finite element (FEM) experiments performed on a dipolar superferric magnet for high uniformity (magnetic) field usable in particle accelerators. First, we address the magnetic field problem, as the main purpose of the superconductor magnet is to provide for a highly uniform, high flux density magnetic field. Then, the heat transfer problem is investigated. As radiation heat transfer is of concern in this application two-dimensional models may not produce accurate, realistic results. Therefore our study is based on a three dimensional geometry abstracted from the CAD design of the prototype. The numerical simulation results unveil the magnetic field spectrum and the heat transfer paths within the structure that may be valuable in optimizing the magnet´s design.
