To achieve this level of precision, the magnetic field seen by the muon must be know at fraction of a ppm level, which puts limits on the required magnetic field uniformity. In addition to the mechanical adjustments made to magnet pole tips, a set of 200 trim coils were added to the ring. These coils form concentric rings with 100 on the top pole and 100 on the bottom. Measurements of the remaining integrated filed errors were made using NMR probes. The use of these trim coils to reduce the remaining higher order field errors will be discussed.
