Magnetic and mechanical optimization of a sextupole magnet prototype

This paper presents the modeling and optimal design of a sextupole magnet prototype for the High-Energy Storage Ring (HESR) of the Facility for Antiproton and Ion Research (FAIR) Project. Magnetic pole shape optimization by way of 2D magnetic modelling and mechanical optimization of magnetic yoke are also presented. Also, the paper analyses the Hall Probe (HP) [2] measurement procedure of the magnetic field in this sextupole magnet prototype for HESR. In these devices, it is of interest to determinate the magnetic field distribution, in the neighborhood of their axis. This distribution is not measured directly, but by using the measurements of magnetic flux density, in a finite number of points selected by users.
