Supply equipment to the new NBH system for the TCV tokamak

The TCV tokamak is equipped with a high power real time-controllable Electron Cyclotron Heating (ECH) system, made of 9 gyrotrons capable of 500 kW RF power. One of the major scientific challenge, the TCV upgrades aimed to, will be the access to a wider range of temperature ratios up to Te/Ti ∼ 1. For this purpose, the TCV heating system will be upgraded by the integration of a Neutral Beam Heating (NBH) system impacting directly on the ion temperature (Ti), while gyrotrons are used to vary mainly the electron temperature (Te). This NB Injector (NBI) will provide 1 MW of neutral power during 2 s into the TCV plasma, at a nominal energy of 30 keV, for an electrical power installed of 2.2 MVA. This paper describes the infrastructure required to implement successfully this novel NBI at CRPP premises.
