The first application of the HIBP diagnostics for co-NBI plasma potential measurement in the TUMAN-3M tokamak
Article
  • Jan 2022
The heavy ion beam probe (HIBP) diagnostics at the TUMAN-3M tokamak was updated to provide measurements in the regime with neutral beam injection co-directed with plasma current (co-NBI). By means of HIBP, plasma potential measurements in the center of plasma were carried out. Plasma potential evolution in the discharge with the LH transition (tran...

... In the present experiments with co-NBI, we do not see the L-H transition if only the co-NBI pulse is not accompanied by a short pulse of gas puffing. The measurements of the BIV line also show no toroidal rotation [27]. It may be explained by a better confinement of fast ions in the co-NBI scenario, hence a lower fast ion loss current and toroidal torque. ...
