A reconfigurable miniaturized transducer based on rotating coils for testing particle accelerator magnets

In this paper, first, conventional design criteria are recalled. Then, the design of the reconfigurable transducer based on four coils to suppress undesired field harmonics, from dipole up to decapole, is illustrated. The possibility of using both radial and tangential geometry, without affecting compensation quality, is highlighted too. Finally, a metrological analysis about the transducer manufacturing is reported, proving that the uncertainty arising from the PCB production is made negligible.
