Mn. Achasov et al., ABSOLUTE ENERGY CALIBRATION OF THE SND DETECTOR CALORIMETER BY COSMICMUONS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 379(3), 1996, pp. 505-506
The SND NaI(Tl) calorimeter calibration procedure based on the use of
cosmic muons is described. With such a calibration the measured resolu
tion for 500 MeV electrons at the VEPP-2M collider is 6.4% (rms).
