| dc.description.abstract | The design of magnetic cores can be carried out bytaking into account the optimization of different parameters inaccordance with the application requirements. Considering thespecifications of the fast field cycling nuclear magnetic resonance(FFC-NMR) technique, the magnetic flux density distribution,at the sample insertion volume, is one of the core parametersthat needs to be evaluated. Recently, it has been shown that theFFC-NMR magnets can be built on the basis of solenoid coilswith ferromagnetic cores. Since this type of apparatus requiresmagnets with high magnetic flux density uniformity, a new typeof magnet using a ferromagnetic core, copper coils, and supercon-ducting blocks was designed with improved magnetic flux densitydistribution. In this paper, the designing aspects of the magnetare described and discussed with emphasis on the improvement ofthe magnetic flux density homogeneity(ΔB/B0)in the air gap.The magnetic flux density distribution is analyzed based on 3-Dsimulations and NMR experimental results. | pt_PT |
