"Electron Bernstein Wave Studies in MAST"

V. Shevchenko G. Cunningham A. Gurchenko E. Gusakov B. Lloyd M. O’Brien A. Saveliev A. Surkov F.Volpe M. Walsh

There is a comprehensive, closely-interlinked electron Bernstein wave (EBW) programme on MAST covering heating experiments, plasma start-up studies, plasma emission measurements, theory and modelling. In this paper we report on proof-of-principle EBW heating experiments conducted on MAST with a 60 GHz, 1 MW gyrotron complex. A 28 GHz (200 kW) EBW s…

"DEVELOPMENT OF ELECTRON BERNSTEIN WAVE RESEARCH IN MAST"

Burning plasma spherical tokamaks (STs) rely on off-axis current drive (CD) and nonsolenoid start-up techniques. Electron Bernstein waves (EBWs) may provide efficient off-axis heating and CD in high-density ST plasmas. EBWs may also be used in the plasma start-up phase because EBW absorption and CD efficiency remain high even in relatively cold pla…
