The rotating-coil magnetometer is a standard device 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 large aspect ratio (> 3:1) the cylindrical domain covers only a portion of the magnet bore and therefore a sampling technique is required, using the single-stretched wire or a moving fluxmeter. The method presented in this paper concerns the extraction of multipoles in the rectangular problem domain by using boundary data.

Abstract
The rotating-coil magnetometer is a standard device 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 large aspect ratio (> 3:1) the cylindrical domain covers only a portion of the magnet bore and therefore a sampling technique is required, using the single-stretched wire or a moving fluxmeter. The method presented in this paper concerns the extraction of multipoles in the rectangular problem domain by using boundary data.File in questo prodotto:
