Electron cyclotron resonance heating (ECRH) experiments have started on the TCV tokamak with the use of 1 MW, X2 heating. The ECW system installation is continuing and will eventually provide 3 MW X2 and 1.5 MW X3. The study of the effects of different heating localization involves: the mobile mirrors of the launcher; the large vertical room for displacing the plasma in the TCV vessel; the radial displacement of the cyclotron resonance with magnetic field. Initial studies of heating and confinement have concentrated mostly on close-to-circular plasmas to allow the largest variation of beam-plasma geometry and to allow comparison with earlier results on other machines, a necessary first step before investigating more strongly shaped plasmas.
