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 T-e/T-i similar to 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 (T-1), while gyrotrons are used to vary mainly the electron temperature (T-e). This NB Injector (NBI) will provide 1 MW of neutral power during 2 s into the TCV plasma, at a nominal energy of 30 key, for an electrical power installed of 2.2 MVA. This paper describes the infrastructure required to implement successfully this novel NBI at CRPP premises. (C) 2015 Elsevier B.V. All rights reserved.
