Abstract
In the most recent measurement of the muon’s magnetic anomalous moment at Brookhaven National Laboratory (BNL), a three standard deviation discrepancy was found between its measured and predicted value. The experiment will be repeated at Fermi National Accelerator Laboratory (FNAL) with four times more precision to prove whether physics beyond the Standard Model is responsible for the observed difference. The high precision measurement requires the muon g-2 magnetic field to be made as homogeneous as possible by applying thousands of iron shims along the steel pole pieces that shape the field. This multitude of shims, however, is hard to catalogue and generates significant gradients for the nuclear magnetic resonance (NMR) probes that measure the field. Data on shimming components was transferred to a MySQL database where it could be optimally stored and analyzed. Acceptable free induction decay (FID) signals from the probes were produced by placing gratings of iron strips on pole surfaces. This will make the g-2 measurement more sensitive to virtual particles and forces, including those that may be currently undiscovered.
