The concept of the array is to simultaneously record the electromagnetic and hadronic components of extensive air showers (EAS) with EN detectors. To estimate the number of hadrons in an EAS, the array detectors record secondary thermal neutrons delayed relative to the shower front. Some of the delayed pulses are created by the simultaneous passage of several charged particles through the scintillator (the signal from one particle lies below the detection threshold) and by the photomultiplier noise. We propose a neutron pulse separation method for EN detectors using convolutional neural networks and make a comparison with the baseline method being currently applied at the installation.</p></abstract><trans-abstract xml:lang="ru"><p>В рамках проекта LHAASO (Large High Altitude Air Shower Observatory) в Китае создается установка ENDA (Electron Neutron Detector Array). Концепция установки состоит в одновременной регистрации электромагнитной и адронной компонент широких атмосферных ливней (ШАЛ) с помощью эн-детекторов. Для оценки количества адронов в ШАЛ детекторы установки регистрируют вторичные тепловые нейтроны, задержанные относительно фронта ливня. При этом часть задержанных импульсов создается одновременным прохождением нескольких заряженных частиц через сцинтиллятор (сигнал от одной частицы лежит ниже порога регистрации), а также шумами фотоумножителя. В работе предлагается метод выделения нейтронных импульсов для эн-детекторов с применением сверточных нейронных сетей и проводится сравнение с базисным методом, применяемым в настоящее время на установке.</p></trans-abstract><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Yu.
