Recent Progress on the Muon g-2 Experiment at Fermilab

The Muon g-2 experiment measures the anomalous magnetic moment of muon. The previous measurement at Brookhaven National Laboratory, experiment E821, completed in 2001 found a greater than 3σ discrepancy from the predicted value. The new generation Muon g-2 experiment at Fermi National Laboratory is expected to accumulate 21 times more statistics and achieve a factor of four improvement in the precision with an upgraded apparatus and reduced systematic uncertainties. With both improvements from experiments and theoretical calculations, a more precise test of the Standard Model value will be made. The experiment construction was completed and the commissioning run successfully finished in Summer 2017. The physics data taking will begin in early 2018.
