The shapes of the liquid‑xenon calorimeter’s output electric signals differ substantially from event to event, thus an additional error is added to the measured signal arrival time even when a constant‑fraction discriminator is used. For measuring the arrival time of the liquid‑xenon calorimeter’s signals a special digital signal processing algorithm has been developed which allows one to reduce the error of signal arrival time determination added by the difference of signals' shapes.
