Description
The Muon g-2 experiment at Fermilab measures the muon magnetic moment anomaly in order to test a potential discrepancy between the experimental value and the Standard Model prediction. During the experiment, muons traveled through a 15-meter-diameter magnetic storage ring, with the magnetic moment anomaly revealed through the ratio between anomalous muon precession frequency and the strength of the magnetic field in the ring. To achieve the precision goal for the experiment, the ~1.45 Tesla magnetic field needed to be evaluated within 70 parts per billion. The magnetic field was mapped and tracked using nuclear magnetic resonance probes inside and around the ring, with extensive calibration and interpolation studies performed to convert the measured field into the field experienced by the muons. This presentation will provide an overview of the magnetic field measurement and analysis techniques implemented in Muon g-2 to achieve this level of precision.
