The measured magnetic sensitivities of these complex geometries can be significantly lower than the predicted values calculated by commonly-used material-based models. In this paper, we suggest a new approach beyond the present material based models. Indeed, both the ambient magnetic field orientation and cavity geometry have a significant impact on the cavity performance degradation due to magnetic trapped flux. Experimental data are presented, and a new model to interpret the geometrical effect is introduced, assessed and shows as well very good agreement with data from the literature.}}, }
