Challenge in reaching 10/sup /minus/7/ precision: Magnetic field, counters and hadronic contribution
Morgan May · University of North Texas Digital Library (University of North Texas) · 1988
Determining the muon magnetic moment anomaly, a/sub ..mu../, to .35 ppM will open a window on physics at a mass scale which is not now accessible to high energy experiments. Measurements of magnetic field and spin precession frequency free from systematic error at the 10/sup /minus/7/ level are required to attain this goal. Approaches to these problems are discussed. A novel method of precision measurement of magnetic field using the cyclotron frequency of heavy ions is outlined. To fully utilize the great experimental precession of the planned measurements of a/sub ..mu../, knowledge of the hadronic contribution to a/sub ..mu../ must be improved. The status of experiments leading to such an improvement is reported. 14 refs. 3 figs.
