摘要: Abstract The Spherical Neutral Detector (SND) operates at VEPP-2M collider in Novosibirsk studying e + − annihilation the energy range up to 1.4 GeV. consists of a fine granulated spherical scintillation calorimeter with 1632 NaI(Tl) crystals, two cylindrical drift chambers 10 layers sense wires, and muon system made streamer tubes plastic counters. detector design, performance, data acquisition processing are described.
