B. Adeva et al., MEASUREMENT OF THE POLARIZATION OF A HIGH-ENERGY MUON BEAM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 343(2-3), 1994, pp. 363-373
A muon beam polarimeter has been built for the SMC experiment at the C
ERN SPS, for muon energies of 100 to 200 GeV. The beam polarisation is
determined from the energy spectrum of positrons from the decay mu+ -
-> e+ nu(e)numuBAR. A polarisation of -0.82 is measured with a relativ
e systematic accuracy of 3%.
