Abstract
We present a new method for the characterization of 3D Helmholtz coils with respect to their field or-thogonality errors. It is based on 3D field sensing inside the homogeneity region using conventional 3D Hall sensors that need to be precisely orthogonality calibrated in a first step. Repeated measurements with different such sensors are used to confirm the algorithmically determined 3D coil field tolerances.Upon finding discrepancies, we discovered environmental influences affecting the determination of the coil orthogonality angle errors and propose means to minimize their impact.
