Подробно описана конструкция экспериментального устройства применяемого для проведения термодесорбционных экспериментов с графитовыми тайлами токамака КТМ. Описана методика проведения термодесорбционных экспериментов. Приведены зависимости газовыделения из графитовых тайлов от времени в процессе их отжига при линейном нагреве со скоростью 3,5 °С/мин до температуры 450-480 °С в режиме постоянной откачки высоковакуумным насосом. Представлен краткий анализ экспериментальных данных. Предложены рекомендации по технологии подготовки графитовых тайлов перед монтажом их в вакуумную камеру токамака КТМ.</p></abstract><trans-abstract xml:lang="en"><p>This article describes the preparation and conduct of experiments on atmospheric gas release from graphite elements (tiles) of the KTM tokamak during their heating to a temperature of 450-480 °С. The paper describes the design of the experimental device used for thermal desorption experiments with graphite tiles of the KTM. The method of conducting thermal desorption experiments is described. The time dependence of gas release from graphite tiles during their annealing at linear heating at a rate of 3.5 °C/min to a temperature of 450-480 °C in the constant pumping mode with a high-vacuum pump are given. A brief analysis of experimental data is presented. Recommendations on the technology of preparing graphite tiles before their mounting in the vacuum chamber of the KTM tokamak are proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>графитовые элементы</kwd><kwd>токамак</kwd><kwd>десорбция</kwd><kwd>атмосферные газы</kwd><kwd>температура</kwd><kwd>эксперимент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>graphite elements</kwd><kwd>tokamak</kwd><kwd>desorption</kwd><kwd>atmospheric gases</kwd><kwd>temperature</kwd><kwd>experiment</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках реализации НТП КТМ по теме «Разработка и экспериментальное обоснование инновационных технологий для создания термоядерного реактора»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mazzitell, G.
