TL;DR: The TFTR tokamak has reached its original machine design specifications (Ip=2.5 MA and BT=5.2 T) by operating at low plasma current and low density (ne approximately=1*1019 m-3), high ion temperatures (9+or2 keV) and rotation speeds (7*105 m/s) have been achieved during injection.

TL;DR: In this paper, the effect of beam orientation on tokamak performance has been studied and a neutral beamline was re-oriented from injecting co-parallel to counter parallel, which will increase the available balanced neutral injection power from 14 MW to 27 MW.
