Reconstruction of plasma edge density profiles from LiI(2s-2p) emission profiles
The injection of 10-100 keV Li(0) diagnostic beams into magnetically confined fusion plasmas causes collisionally induced LiI emission at 670.8 nm, in close relation to the edge plasma electron density. A numerical method for quantitative reconstruction of the plasma density exclusively from relative LiI 670.8 nm emission profiles as measured along the diagnostic beam has been developed, involving all relevant collisional interactions of the Li atoms with plasma constituents. The applicability of the described algorithm is illustrated by experimental results obtained for the TEXTOR tokamak edge plasma.
