Abstract
Abstract
Lithium capillary-porous system (CPS) as a mat between molybdenum grids fixed in a molybdenum module was tested in PLM plasma device for 3 hours in a steady state helium discharge with plasma parameters relevant to scrape-off-layer and divertor plasma of large tokamak. The plasma load on the CPS was of 1 MW / m2 led to surface heating up to 700 °C and vaporization of lithium to plasma. Lithium ions was registered by optical emission spectra from plasma. The redeposition of vaporized lithium was detected on the PLM in-vessel components. Inspections of CPS modules after plasma irradiation did not reveal any damage of molybdenum grids.
