It has a time resolution of about 1.3 ns at an energy deposition in the calorimeter crystal of 100 MeV and an amplitude resolution of about 250 keV. The new channel is designed, in particular, for the study of the e<sup>+</sup>e<sup>-</sup> n process at the VEPP-2000 e<sup>+</sup>e<sup>-</sup> collider.
