Abstract
A Hall probe device has been built to measure the radial component of the m agnetic field in the muon (g-2) storage ring at Brookhaven National Laborat ory. The ultraprecise (g-2) magnet provides a dominantly vertical magnetic field of about 1.45 T. In order to limit the vertical shift of the muon orb it, the average radial field component should be no more than 5 x 10(-5) of , the vertical field. Our measurements with the Hall probe device achieved an accuracy of 1 x 10(-5). which is one of the most precise measurements wi th Hall probes. This provides adequate accuracy for shimming and control of the radial field. (C) 2001 Elsevier Science B.V. All rights reserved.
