Performance analysis of miniaturized PCB coils for small-aperture magnet qualification

The metrological performance of a magnetic field transducer, consisting of a fyberglass cylinder hosting three PCB coils with a diameter of 7.5 mm, is analyzed. The transducer aims at facing the more challenging goals expected in the near future of particle accelerators, involving magnet apertures smaller than 1 cm. Main intents are to gain useful feedback to designers for optimizing the manufacturing and improving the metrological performance of the transducer.
