A proposed implementation of direct ion heating on the TCV by the installation of a neutral beam injection (NBI) with a total power of would permit an extension of the accessible range of ion to electron temperatures () to well beyond unity, depending on the NBI/ECH mix and the plasma density. A NBI system would provide TCV with a tool for plasma study at reactor relevant ratios ∼1 and in investigating fast ion and MHD physics together with the effects of plasma rotation and high plasma ˇ scenarios. The feasibility studies for a NBI heating on TCV presented in this paper were undertaken to construct a specification for the neutral beam injectors together with an experimental geometry for possible operational scenarios.1.
