A high-power mock-up of an Ion Cyclotron Resonance Heating Travelling Wave Array antenna has been validated in the CEA/IRFM TITAN Testbed. Up to 2 MW/3s (Max Generator RF power) and 500kW/60s were achieved at 55.5 MHz. Electrical responses are as expected by modelling: the antenna is wide-band (10 MHz) and has a lower electric field than a conventional antenna (around 20 kV for 2 MW).

This article published in Nature Physics 12, 14-17 (2016) by D. Mazon, C. Fenzi and R. Sabot, is related with the problem of sustaining and measuring temperature in fusion plasmas. This challenging task requires different heating systems and diagnostic tools. Information on the spatial distribution of temperature is one of the key elements for improving and controlling plasma performance.

Turbulence is a major issue in tokamaks, in particular as it drives energy from the core of the plasma to the edge of the plasma. This undesired energy transport is one of the elements which account for the difficulty of maintaining fusion-favourable conditions in the heart of tokamaks. The introduction of a specific perturbation (EGAM) could contribute to reduce turbulence.
