Commissioning of the heating neutral beam injector on the TCV tokamak

This paper will concentrate on the description of the commissioning of the NBI system at the Swiss Plasma Center (SPC) site. The main results obtained during the first operation phase with TCV are presented in Karpushov et al. (2016) [3]. The stages went through from the installation of the main auxiliaries (HVPS, RF PS, cooling circuits, cryogenics equipment etc.) up to the final acceptance tests on the plasma targets will be detailed. The measurements and the associated protection interlocks acting on the TCV control system will be described, including also the human safety rules imposed to comply with a safe operation of the injector. To conclude, the next stage to finalize the integration of the NBH on TCV will be briefly developed.
