В качестве базовой триггерной ячейки рассматривается состоящая из 2 × 2 кристаллов область, значение суммарной амплитуды сигнала в которой передается для обработки в триггерную систему. На основе моделирования методом Монте-Карло определено оптимальное количество триггерных ячеек, которые должны быть отнесены к кластеру для восстановления энергии попавших в калориметр частиц в режиме реального времени.</p></abstract><trans-abstract xml:lang="en"><p>In order to improve the energy and coordinate resolution of the neutral trigger of the СMD-3 detector, it is proposed to use a clustering algorithm based on overlapping “windows” of trigger cells. The window of 2 × 2 crystals is considered to be a single trigger cell, and its signal amplitude value is sent for processing by the trigger system. Based on MonteCarlo simulation, the optimal number of trigger cells to assign to the cluster for energy reconstruction of particles hitting the calorimeter in real time was determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>физика элементарных частиц</kwd><kwd>нейтральный триггер</kwd><kwd>триггерная ячейка</kwd><kwd>эффективность запуска</kwd><kwd>детектор КМД-3</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elementary particle physics</kwd><kwd>neutral trigger</kwd><kwd>trigger cell</kwd><kwd>trigger efficiency</kwd><kwd>detector CMD-3</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского научного фонда (грант № 23-42-10025, https://rscf.ru/project/23-42-10025/) и Белорусского республиканского фонда фундаментальных исследований (грант № Ф23РНФ-118).</funding-statement><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation (grant no. 23-42-10025, https:// rscf.ru/project/23-42-10025/) and the Belarusian Republican Foundation for Fundamental Research (grant no.
