Abstract

Parameterizations of signals from the towers of the electromagnetic calorimeter of the MPD/NICA detector, aimed at an estimation of the time resolution of the calorimeter, are considered. Optimal parameters of the timing are determined within the constant fraction method. In test measurements with cosmic rays, a time resolution of 1.3–0.8 ns was obtained depending on the signal amplitude. These results show the possibility of relative calibration of the time parameters of calorimeter towers using cosmic rays.
