摘要：

In particle accelerators, "field markers" provide a digital trigger when the magnetic field crosses a given threshold. In this paper, the metrological characterization of a magnetic field marker, based on a ferrimagnetic resonance transducer referencing the flux sensed by a coil, is reported. The experimental results of a validation test campaign at the European Organization for Nuclear Research (CERN) to test the marker in static as well as fast ramping fields (up to 2.5 T/s) are illustrated. The repeatability of +/- 4 mu T attained in the range (60 to 100) mT is very promising to increase the performance of the Proton Synchrotron accelerator at CERN.
