Получены для ускоренных позитронов: спектры по их энергии; зависимости максимумов этих спектров от начального сдвига фазы ускоряющей позитроны СВЧволны и от энергии ускоренных позитронов; фазовые распределения ускоренных позитронов. Найдены спектры начальных энергий позитронов, существенных в получении ускоренных позитронов в максимуме их спектра. Сопоставлены эффективности получения позитронов с и без их ускорения на ЛУЭ для исследований гигантских резонансов в атомных ядрах.</p></abstract><trans-abstract xml:lang="en"><p>For multisectional traveling wave linear electron accelerators, the acceleration of positrons from an electron-bombarded intersectional converter target is considered by comparison of the model with an experiment. For the accelerated positrons and their energy spectra, the dependence of maxima of these spectra on the initial phase shift of a microwave (which accelerates the positrons) and on the energy of accelerated positrons and the phase distributions of these positrons are obtained. The spectra of the initial positron energies are found, which are essential in obtaining the accelerated positron current at the maximum of their spectrum. To study giant resonances in atomic nuclei, the efficiencies of obtaining positrons with and without their acceleration at electron LINACs are compared.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>линейные многосекционные ускорители электронов на бегущей волне (ЛУЭ)</kwd><kwd>пучки электронов и позитронов в ЛУЭ</kwd><kwd>динамика ускорения позитронов в секциях ЛУЭ</kwd><kwd>гигантские резонансы в атомных ядрах</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multisectional linear accelerator of electrons on a traveling wave (LINAC)</kwd><kwd>beams of electrons and positrons in LINAC</kwd><kwd>dynamics of positron acceleration in LINAC sections</kwd><kwd>giant resonances in atomic nuclei</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">Rachek I.A. et al. // Proc.
