Abstract:In this assignment the performance is studied of magnetic shields made from a combination of two materials, a high-μ metal called CryoPerm and the superconductor Nb. These shields are needed to create a low magnetic field environment for the proper functioning of detectors whose performance depends on magnetic field. The shields are usually designed with the aid of numerical models. However, in the design of high-performance shields the effect of remanence is of particular interest for both high μ metal and superconductors, since it can lead to field contributions that are difficult to model. This assignment will be done in two parts. First an experimental validation of finite element and analytical models of relatively complex shield structures is made, especially looking at the effect of remanence compared to the model results. Second, we attempt to set up a model that describes flux trapping in a superconductor while cooling through its transition temperature.
