При обработке используется изображение маски, получаемое на сцинтилляторе от рентгеновской вспышки плазмы мишени, что позволяет восстановить положения отверстий маски. Приведена схема измерений эмиттанса пучка ионов углерода, извлекаемого из лазерной плазмы, создаваемой импульсами CO2-лазера при плотности потока излучения 1011 Вт/см2. Приведены некоторые результаты обработки и вычисления эмиттанса пучка ионов C+.</p></abstract><trans-abstract xml:lang="en"><p>Description of computer code developed for processing images obtained in pepper-pot emittance measurement technique, which allows estimating emittance in single measurement. The code uses pepper-pot mask image on a scintillator screen obtained by means of laser-plasma radiation. This image is used to find positions of holes of the mask and its rotation angle. Pepper-pot techinique is applied to measure emittance of carbon ion beam extracted from laser produced plasma, generated by CO2-laser pulses with the focal power density on the target of about 1011 W/cm2. Results of image processing and calculating emittance are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерный источник ионов</kwd><kwd>CO2-лазер</kwd><kwd>измерение эмиттанса</kwd><kwd>методика pepper-pot</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser ion source</kwd><kwd>CO2-laser</kwd><kwd>emittance measurement</kwd><kwd>pepper-pot technique</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">Barabin S.V. et al. // Proc. 26th Russian Particle Accelerator Conference. 2018.
