Next generation muon g-2 experiment at FNAL

has stimulated much theoretical and experimental efforts over more than six decades. The last experiment at Brookhaven National Laboratory, Upton, NY, USA obtained a value more than three standard deviations larger than predicted by the Standard Model of particle physics, and is one of the strongest hints for physics beyond the Standard Model. A new experiment at Fermi National Accelerator Laboratory, Batavia, IL, USA to measure a

with fourfold increased precision to 140 ppb is currently in its commissioning phase. While the new experiment will reuse the 1.45 T superconducting muon storage ring which was shipped from Brookhaven National Laboratory, most of the other instrumentation of the experiment will be new. This will allow the experiment to make efficient use of the significantly higher number of muons available at the new muon campus. We discuss the general status of the experiment and in particular focus on the improved tools available to homogenize and determine the magnetic field in the muon storage ring.
