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