The single-particle approximation is used to obtain analytical expressions that connect the electric potential distribution and the angular mass spectrum. A mathematical algorithm is described that allows one to recover the distribution of electric potential from the given shape of the mass spectrum. It is shown that the local inhomogeneity of the electric potential profile allows one to achieve the deposition of mass groups in the diametrically opposite regions of the separator. Data is presented that confirms the possibility of creating experimentally both the positive and the negative local inhomogeneity of the potential. The results of this work can be used to increase the efficiency of the process of plasma mass separation of ions of different elements.</p></abstract><trans-abstract xml:lang="ru"><p>Рассматривается влияние пространственного распределения электрического потенциала на разделяющие свойства плазменного масс-сепаратора, работающего в конфигурации скрещенных радиального электрического и продольного магнитного полей. В рамках одночастичного приближения были получены аналитические выражения, связывающие распределение электрического потенциала и угловой масс-спектр. Описан математический алгоритм, при помощи которого можно восстановить распределение электрического потенциала по заданной форме масс-спектра. Показано, что локальная неоднородность формы электрического потенциала позволяет добиться осаждения массовых групп в диаметрально противоположных областях сепаратора. Приведены данные, подтверждающие возможность создания в эксперименте как положительной, так и отрицательной локальной неоднородности потенциала. Результаты работы могут быть использованы для повышения эффективности процесса плазменной масс-сепарации ионов различных элементов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>electric potential distribution in plasma</kwd><kwd>mass separation of ions of heavy metals</kwd><kwd>crossed electric and magnetic fields</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>распределение электрического потенциала в плазме</kwd><kwd>масс-сепарация ионов тяжелых металлов</kwd><kwd>скрещенные электрическое и магнитное поля</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Стратегия развития атомной энергетики России в первой половине XXI века.
