        <p>Проведен анализ спектра синхротронного излучения электронов, совершающих бетатронные колебания и ускоряемых по механизму прямого лазерного ускорения в ионном канале, созданном мощным лазерным импульсом в плазме околокритической плотности. Показано, что характеристики спектра излучения отражают характерные параметры пространственных и энергетических распределений электронов.  Это открывает возможность диагностики энергетического спектра электронов в плазменной мишени по спектру синхротронного излучения таких электронов, что важно ввиду возможных отличий такого спектра от спектра вылетевших из плазменной мишени электронов.</p>

      <abstract xml:lang="en" abstract-type="summary">
        <p>An analysis is made of the spectrum of synchrotron radiation of electrons executing betatron oscillations and accelerated by the mechanism of direct laser acceleration in an ion channel created by a powerful laser pulse in a plasma of near-critical density. It is shown that the characteristics of the radiation spectrum reflect the characteristic parameters of the spatial and energy distributions of electrons. This opens up the possibility of diagnosing the energy spectrum of electrons in a plasma target from the spectrum of synchrotron radiation of such electrons. This is important in view of the possible differences between such a spectrum and spectrum of electrons emitted from the plasma target.</p>
