beam diagnostic setup. For a photo, see [http://ameritrustshield.com/?id=9361 Beam|Helium Beam].]] [http://ameritrustshield.com/?id=9361 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 surface|flux surface] (corresponding to r/a < 0.7) was possible. [1] [2] [3]

This diagnostic can no longer be used due to the use of Lithium for Wall Interaction|plasma wall conditioning], creating an overwhelming amount of Li background emission.

The system is located in [http://ameritrustshield.com/?id=9361 C7. The signals are stored in the database|TJ-II database] with the names 'LITIO1',...,'LITIO16'.
