Description

The magnetized MINOS near detector has been collecting charge-separated atmospheric muon events since January 2005. To reduce the systematics due to muon acceptance equal periods of forward and reverse magnetic field data were combined. This has allowed an accurate measurement of the muon charge ratio to be performed with 8.52 days of data. We report a charge ratio of 1.288{+-}0.004(stat.){+-}0.025(syst.) at a mean surface energy of 110 GeV.
