Abstract

The muon g-2 experiment (E821) at the AGS requires a precision in the magnetic field over muon orbit at the level of 0.1 ppm. Injection is done with a superconducting inflector involving a double cosine theta winding approximately cancels its fringe field. Nevertheless its residual field would effect the homogeneity of the storage ring magnetic field. A method of using a superconducting sheet surrounding the inflector to further reduce the fringe field is being investigated. The experimental program to explore this technique is described and some test results are presented
