Description
The Muon $g-2$ experiment at Fermilab will measure the muon’s anomalous magnetic moment, $a_{\mu}$, to 140 parts-per-billion. Modern calculations for $a_{\mu}$ differ from the current experimental value by 3.6$\sigma$. Our effort will test this discrepancy by collecting 20 times more muons and implementing several upgrades to the well-established storage ring technique. The experiment stores $\approx 10^{4}$ muons at a time in a 7-meter-radius superconducting electromagnet with a highly uniform 1.45-Tesla magnetic field. In this poster I will summarize the magnetic field uniformity requirements needed to achieve our precision goals for the determination of $a_{\mu}$. The commissioning of the magnet and the nuclear magnetic resonance probes used to measure the magnetic field will be described. I will detail the procedure utilized to both measure and maximize the uniformity of the magnetic field, and report on the current status of the magnet.
