The New Muon g-2 E989 Collaboration at Fermilab will measure the muon anomalous magnetic moment a&mgr; to a precision of 140 ppb, which represents a four-fold improvement in the experimental precision of the current value. Central to the E989 experiment is the muon storage ring magnet previously used by the E821 Collaboration at Brookhaven National Laboratory. The storage ring produces a highly precise magnet field. Muons will circulate the storage ring within a vacuum, and as the spin angular momentum of each muon precesses about the axis of the applied magnetic field, the muons will decay into positrons emitted preferentially along the instantaneous spin direction of the parent muon. Detectors will measure the energy and the number of high-energy positrons detected as a function of time, and the data will be analyzed to understand how much the muon's spin angular momentum is precessing. Specifically, the muon anomalous spin precession frequency &ohgr;a and the average magnetic field 〈B〉 felt by the precession muons will be precisely measured by tracking detectors to extract the muon anomaly at the required precession. This paper focuses on the design, placement, and testing of the tracking detectors, and the development of the tracking detector simulation software.
