Процессы возбуждения и распространения поверхностных акустических волн в La3Ga5,3Ta0,5Al0,2O14 исследованы методом двухкристальной рентгеновской дифрактометрии на источнике синхротронного излучения BESSY II. На основе анализа дифракционных спектров акустически промодулированных кристаллов продемонстрировано, что интенсивности дифракционных сателлитов на кривой качания кристалла ЛГТА изменяются по осциллирующему закону с увеличением амплитуды входного сигнала на ВШП (увеличение амплитуды ПАВ). На основе анализа дифракционных спектров определены скорости распространения ПАВ в Y−срезе (V = 2220 м/с), X−срезе (V =  2340 м/с) и yxl/+36°−срезе кристалла ЛГТА (V = 2622 м/с). Проведено исследование распределения дифрагированной рентгеновской интенсивности по поверхности кристалла, промодулированного ПАВ, что позволило построить карту распределения акустического волнового поля на поверхности Y−, X− и yxl/+36°−срезов кристалла LGTA. Продемонстрировано, что в кристалле ЛГТА отсутствует снос потока акустической энергии в Y−срезе, а в X− и yxl/+36°−срезах снос потока акустической энергии составляет 6,3° и 4,0° соответственно. </p></abstract><trans-abstract xml:lang="en"><p>Development and search for new advanced materials of the lanthanum gallium silicate group with unique thermal properties is of great importance for the development of acoustoelectronics based on volume and surface acoustic waves. The processes of surface acoustic wave excitation and propagation in the La3Ga5.3Ta0.5Al0.2O14 crystal was studied using a double−crystal X−ray diffractometer with a BESSY II synchrotron radiation source. The X−ray diffraction spectra of acoustically modulated crystals were used to measure the surface acoustic wave velocity and power flow angles in different acoustic cuts of the La3Ga5.3Ta0.5Al0.2O14 crystal. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>пьезоэлектрический кристалл</kwd><kwd>поверхностные акустические волны</kwd><kwd>двухкристальная рентгеновская дифрактометрия.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>piezoelectric crystal</kwd><kwd>surface acoustic wave</kwd><kwd>synchrotron radiation</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">Da Cunha, M.
