Lithium deposits from the T-10 tokamak after experiments with lithium capillary-porous system

摘要

The structure of lithium deposited specimens at the T-10 tokamak vessel after examination of lithium capillary porous system were analysed. Scanning electron microscopy have been used to analyse the deposits. Composites of lithium carbonate Li_xCO_y have been found by analysis. Plasma irradiation of these lithium specimens have been carried out in the PLM plasma device with plasma parameters similar to the tokamak divertor plasma. Stationary plasma load up to 1 MW/m~2 during 200 minutes in the PLM provided the change of surface morphology revealed by postmortem analysis.
