Description
Summary:A possible application of a lithium emitter-collector scheme to the T-15MD tokamak is considered. 2D simulations with the SOLPS4.3 code package indicate that the outer midplane is the optimal position for the lithium emitter. In the magnetic configuration analysed, lithium deposition is primarily localized in the upper outer divertor. Lithium radiation enhancement due to non-coronal effects for the case studied is about a factor of 6. However, although much higher than normally observed for higher Z impurities (such as neon), this enhancement is clearly insufficient to provide significant energy dissipation, unless the lithium inventory in the edge becomes close to the deuterium one.
