• The Spherical Neutral Detector 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 super(+)e super(-) collider. The results of the muons and pions detection efficiency measurements are presented. These measurements are performed using e super(+)e super(-) arrow right mu super(+) mu super(-), e super(+)e super(-) arrow right [pi] super(+)[pi] super(-), e super(+)e super(-) arrow right [pi] super(+)[pi] super(-)[pi] super(0) [pi] super(0), e super(+)e super(-) arrow right e super(+)e super(-) processes and cosmic muons. Efficiency for muons is 95.5% for the energies 0.6-1.0 GeV and becomes much lower in energy range 0.45-0.60 GeV. Pions detection efficiency varies from 0 at 0.4 GeV to 56% at 1.0 GeV. Probability of the muon system hit from electon/positron is no more than 0.43%.
