N. Doble et al., THE UPGRADED MUON BEAM AT THE SPS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 343(2-3), 1994, pp. 351-362
The SPS muon beam, recently upgraded for the Spin Muon Collaboration e
xperiment, is described. The basic concepts of the beam design are pre
sented. The measured beam flux and muon halo rates, spot sizes and ave
rage muon polarisation are reported and the observed performance is co
mpared with Monte Carlo simulations.
