SND Experiment

There are three major periods in evolution of the SND experiment; Previous experiment with ND[3] (predecessor of SND) has shown that the e+e− annihilation in the final states with neutral particles in the energy range 2E=0.4-1.4 GeV is mediated by the processes which need to be studied in more details.

The detector design is illustrated in the R-θ view and 3-D plot of the NaI(Tl) calorimeter segmentation.

Unique features of the SND and its sensitivity to the neutral particles are defined by the state-of-art NaI(Tl) calorimeter.

Data collected in the SND experiment from 1995 to 2000 corresponds to the integrated luminosity 30 pb−1 spread in the energy range 2E=0.4-1.4 GeV.
