By implanting positive muons in a substance (either gas, liquid or solid), their magnetic moments can be used to sample the magnetic properties of the material. The precession rate can give the magnetic field strength, and the field direction is given away after the muons decay into positrons that are detected. The information obtained from muSR can be complementary to that from other methods such as NMR, ESR, and neutron scattering. A low energy muon surface source is particularly interesting for studying thin films. To date, only four user facilities exist in the world but none in the US. We explore the possibility of using the AGS complex at BNL for a muSR facility for the production of positive surface muons.
