Abstract
| This lecture provides a broad overview of the topic of measurement of the field generated by accelerator magnets. First, the need of magnet testing is put in context by comparing it with numerical modelling and beam-based measurements. Then the most commonly used measurement principles are reviewed including induction, Lorentz force and magnetic resonance-based instruments. A few metrological aspects are highlighted, such as the role of calibration references and the possible impact of recent SI system updates. Finally, some examples are given on the topic of magnetic sensor fiducialization, i.e. calibration of its geometrical position. |
