Measurement of the SMC muon beam polarization using the asymmetry in the elastic scattering off polarized electrons

A muon beam polarimeter was built for the SMC experiment at the CERN SPS, for beam energies of 100 and 190 GeV. The beam polarization is determined from the asymmetry in the elastic scattering off the polarized electrons of a ferromagnetic target whose magnetization is periodically reversed. At muon...
