Field Mapping

Introduction
The Model 692 is developed for measurement of the strength and quality of multipole magnet fields, for magnetic centering, and for precise positioning of alignment targets on the magnets. The measurement system has been designed with the aim to perform precise, fast and reliable measurements of series of magnets. Care has been taken to ensure that the mechanical constructions have sufficient stability against or is insensitive to vibrations and thermal expansion. With computerized routines for pre-alignment, harmonic measurement and data analysis, magnetic centering and alignment, the need for operator intervention during the actual measurements and data evaluation is minimized.

The Danfysik Multipole Magnet Measurement System, Model 692, is a high precision device for testing magnetic field quality of multipole magnets.
