TJ-II:Lithium Beam

TJ-II possesses a Lithium beam diagnostic. A thermal Li beam source, located at ∼ 80 cm from the observation region, has been used for the reconstruction of the SOL and edge parameters of the plasmas. A 16 channel photomultiplier array allowed the continuous recording of the radial profile of Li* emission. Detection of the Li* emission up to 8 cm inside the last closed flux surface (corresponding to r/a < 0.7) was possible. [1] [2] [3]
