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.
