Deninger, William James 2012-05-21T15:28:00Z 2012-05-21T15:28:00Z 10000-01-01 1999 Using a muon storage ring located at Brookhaven National Laboratory (BNL), the first year of a continuing four year effort to measure the anomalous magnetic moment of the muon to 0.35 ppm has been completed. The measurement hopes to provide a direct experimental determination of the single loop weak renormalization with 23 percent resolution, and will place more stringent constraints on extensions to the Standard Model. To measure the muon anomaly, polarized muons are injected into a magnetic storage ring and decay into positrons via the parity violating weak interaction. The spin precession rate of the muons in the ring is then determined by measuring energy oscillations of the decay positrons. The rate of oscillation is directly proportional to the magnetic anomaly of the muon. In an effort to measure experimental systematic errors associated with muon phase space in the magnetic storage ring, a system of four straw drift tube tracking chambers, called the traceback detector, was designed and built at the University of Illinois. The detector is responsible for indirectly measuring the muon distribution in the magnetic storage ring by tracking decay positrons backwards into the magnetic storage ring to the point of muon decay. The muon distribution measurement made from 24093 decay positrons during 1997 lead to a magnetic field systematic correction of +0.3093(117)(4613) ppm to the anomalous magnetic moment of the muon. This measurement is the framework of this doctoral thesis.
