Exploring the Effect of Ferroshims on Magnetic Field Homogeneity

Abstract

Shimming is a technique used to achieve a uniform field in superconducting magnets. There are various methods of shimming that can attain different results. For example, one of these methods is the use of ferroshim patterns. Ferroshims can be used for processes that require a very homogeneous field such as nuclear magnetic resonance spectroscopy (NMR). Although it is used in NMR, the specific ferroshim designs used for the technique are hard to find in scientific papers. Therefore, with the goal of comparing the data with theoretical plots, I explored ferroshims by analyzing the field of a superconducting magnet with a 1 mm thick solid ring ferroshim pattern. The results showed an alignment of the theoretical plots and the experimental plots with a small variation. These findings suggest that this ferroshim model could be successful and possibly help optimize shimming techniques. In the future, alternative ferroshim patterns could be explored to analyze their functionality in superconducting magnets and increase field homogeneity.
