    Field Measurement

    The magnetic field performance and quality of multipole magnets (quadrupoles, sextupoles, octupoles, etc.) is normally defined by the integrated main magnetic field component and the relative contribution of higher order harmonic field components with respect to the main component. These parameters may vary as a function of magnetic excitation, and hence will need to be checked at several excitation intervals. An additional quality measure is the variation of the position of the magnetic center with respect to the mechanical center.

    We offer two field measurement systems for mapping and test of magnetic multipole fields:

    Model 690 is a fast rotating coil system providing medium accuracy data on the integrated main magnetic field component, the relative amplitudes of higher order multipole components, and the magnetic center position. This system is optimized for fast throughput of the measurements.

    Model 692 is a slow rotating coil system designed for very high measurement accuracy of the integrated main magnetic field component, the relative amplitudes of higher order multipole components, and the magnetic center position. The system also provide precise data on the angular phases of the main magnetic field component, the higher order components and the magnetic center. This system also allows precision positioning of alignment targets with respect to the magnetic center axis on the magnets.

    Model 694 is a stretched wire system designed to be a very versatile magnet measurement system that can be utilized for field integral magnetic strength measurements, homogeneity measurements and for integrated multipole measurements. Magnetic multipole centering and fiducialization can be performed with very high accuracy.
