 Abstract: The ALEPH-experiment at the LEP e+e- storage ring at CERN has been used to measure the momentum spectrum of cosmic ray muons. ALEPH is located at a vertical depth of 320 m.w.e. underground close to the Jura mountains. The time projection chamber (TPC) of ALEPH with its excellent spatial resolution allows to reconstruct tracks of single and multiple muons with high accuracy. A strong magnetic field of 1.5 Tesla provides the basis of the momentum measurement. About 1.4 Million triggers with single and multiple muon events have been analysed. The obtained muon momentum spectrum and the charge ratio in the range from 80 to 2500 GeV/c is presented. After corrections for energy loss in the overburden the muon spectrum at surface is obtained. The results are compared to results from other experiments.
