Li dust injection experiments into T-10 tokamak

Abstract An improved 0D transport model has been applied to model the deuterium, lithium and carbon densities of T-10 plasmas during Li dust injection. The deuterium recycling coefficient is found to drop from 0.92 to 0.80 during Li dust injection at the expense of higher Z eff values. The dust injection results are compared with the alternative techniques, Li pellet injection and Li evaporation. Dust injection provides the best recycling conditions at the lowest levels of Li consumption.
