Electron-beam welding of the grill flanges of the FTU additional heating systemFunded under: EAEC-FUSION 12C
The FTU is a medium-high magnetic field (8T) tokamak with a radio-frequency (RF) additional heating system (8 MW, 8 GHz) that can heat the plasma to temperatures of fusionistic interest. The RF power is coupled to the plasma by a coupling structure consisting of three grills, each formed in an array of waveguides welded at the terminal flanges by an electron-beam technique. This solution allows highly accurate dimensions and optimum clean-surface conditions at the welded copper joints.
