Field markers in particle accelerators are used to provide a digital trigger when the magnetic field reaches a pre-set threshold. This paper describes the results of a test campaign performed on the extra low energy antiproton decelerator’s main bending dipoles at the European Organization for Nuclear Research (CERN) investigating the behavior of nuclear magnetic resonance (NMRNuclear Magnetic Resonance.

For a high-field marker using high ramp rates, the reproducibility of the signal was found to be better than 3 µT.
