Предложен алгоритм оптимального выбора шага моделирования для неупругого dd-взаимодействия, учитывающий снижение энергии дейтронов на шаге. С использованием закона Линдхарда (при малых энергиях энергетические потери заряженной частицы пропорциональны ее скорости) разработан алгоритм коррекции потерь энергии дейтронов на шаге. Использование этих алгоритмов позволяет ускорить моделирование мишени нейтронного dd-генератора на порядок.</p></abstract><trans-abstract xml:lang="en"><p>When modeling neutron dd-generators, it is necessary to take into account the deuteron energy drop in the simulation step, which leads to a rapid drop in the inelastic dd-interaction cross sections. An algorithm for optimal choice of the modeling step for inelastic dd-interaction is proposed, taking into account the decrease of the deuteron energy per step. Using the Lindhard law (at low energies, the energy losses of a charged particle are proportional to its velocity), an algorithm for correcting deuteron energy loss per step has been developed. Using these two algorithms can speed up the modeling of a neutron dd-generator target by an order of magnitude.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>реакция неупругого dd-рассеяния</kwd><kwd>нейтронные dd-генераторы</kwd><kwd>электронные энергетические потери</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inelastic dd-scattering reaction</kwd><kwd>neutron dd-generators</kwd><kwd>electron energetic losses</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Berger M.J.
