The 3D electrical field maps for various accelerating gaps are used for the central region electrode structure optimization. The accelerating gappositions and other parameters are defined by assuming maximal ion energy gain per turn.The best configuration for 4 basic acceleration regimes was constructed for VINCY cyclotron.The beam dynamics analysis for the new configuration was performed. It was shown that the new configuration has much less beam losses and better ion centering.</abstract><trans-abstract xml:lang="ru">Работа посвящена оптимизации геометрии центральных электродов циклотрона методом обратной трассировки пучка. В качестве электрического поля ускоряющих зазоров используются 3-мерные карты полей, полученные численным образом. Положение ускоряющих зазоров определяется путем минимизации функционала, зависящего от набора энергии частицей при прохождении ускоряющего зазора. В результате моделирования получена оптимальная геометрия центральной области циклотрона VINCY для ускорения четырех типов ионов.</trans-abstract><kwd-group xml:lang="en"><kwd>cyclotron central region optimization</kwd><kwd>backward tracking</kwd><kwd>beam dynamics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>оптимизация центральной области циклотрна</kwd><kwd>динамика пучка</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Chautard F.
