Abstract :
An analysis of erosion products deposited inside the T-10 tokamak vacuum chamber revealed the presence of two groups of substances: carbon films and dust microparticles. Specimens of the carbon films were investigated using scanning and transmission electron microscopy. In terms of microstructure, the films appeared to be either smooth (homogeneous) or globular, that is, formed by globe-shaped microparticles. Dust specimens were also collected and analysed. Particles with count median diameter of 10–15 nm were detected. The deuterium concentration in the sampled erosion products was measured using the SIMS/RGA technique.
