Recent calculations of the lithium vapor box divertor using SOLPS have demonstrated that far Scrape-Off Layer (SOL) baffling and the corresponding far SOL lithium evaporation are unnecessary for divertor performance. The plasma, acting as a virtual b

Comparing lithium vapor box designs in a high heat flux scenario using SOLPS-ITER

Autor: E.D. Emdee, R.J. Goldston

Publikováno v: Nuclear Materials and Energy, Vol 34, Iss , Pp 101335- (2023)

SOLPS calculations of lithium vapor box divertor designs on NSTX-U are presented. Predictive high power simulations (Pheat=10 MW, qpeakunmitigated∼65 MW/m2) are used to compare and contrast two divertor designs. Specifically a baffled “box” div
