Karazin popup.description2 Object of investigation — high temperature plasma in toroidal magnetic traps and influence of plasma factors on the materials for plasma diagnostics. Aim of investigation — to determine the influence of plasma density profile on the fusion yield and to investigate the influence of plasma factors on the properties of materials used for plasma diagnostics. Method of investigations: numerical calculations by using the transport code ASTRA which allow to solve a system of parabolic equations; methods of optical spectroscopy for investigation of massive mirrors and adhesion of thin-film mirrors. At the simulation of plasma transport processes in toroidal magnetic traps there was shown that thinning out the density in tokomak-reactor ITER near the Grinvald boundary could be much higher than that was supposed to be according to contemporary experiments. One of the possible effects is growth of fusion power up to 30%. One of the methods of plasma control in ITER is optical spectroscopy of plasma emission. Forthis it is necessary to create the optical systems of conducting of light from reactor to spectral devices and detectors, which should work in safe zone. Such system includes periscopical devices consisted of windows and observation mirrors. In this report the results of investigations of plasma factors influence on the optical coefficient reflection as massive (cupper and stainless steel) so thin film (cupper and aluminum) mirrors, deposited on the radiation resistant substrate of magnesium aluminate spinel. The data on changes of optical reflection and adhesion in the system thin film-substrate also described. The results of this work could be used for prediction of parameters in the test s tokamak -reactor ITER at the development of commercial fusion reactors based on magnetic configuration of tokomak types and at the development of optical system for plasma diagnostics in such reactors.
