Abstract
Rotating-coil magnetometers are standard devices for measuring integrated magnetic fields of accelerator magnets. The coil intercepts the magnetic flux at a radius given by the dimensions of the measurement shaft that comprises a set of induction coils. For magnets of a rectangular aperture with a large aspect ratio (larger than 3:1) the cylindrical domain will cover only a portion of the magnet aperture. We, therefore, explore an alternative sampling technique using boundary data acquired from a displaced stretched-wire or from a translating fluxmeter. The method presented in this study concerns the reconstruction of the two-dimensional map of the integrated magnetic field distribution in the entire magnet aperture using the measured boundary data.
