Description
The muon system composed of proportional tubes and plastic scintillation counters is described. This system is constructed for the SND detector collecting data at VEPP-2000 e⁺e⁻ collider. The results of the muons and pions detection efficiency measurements are presented. These measurements have been porformed using e⁺e⁻ → μ⁺μ⁻ and e+e⁻ → π⁺π⁻ processes. Efficiency for muons is 94% for the energies 0.6-1.0 GeV and becomes much lower in energy range 0.45-0.55 GeV. Efficiency for pions is preliminary estimated and varies from 5% at 0.5 GeV to 30% at 1 GeV.
