Alfven eigenmode (AE) activity driven by NBI-produced fast ions is observed in TJ-II plasmas. A two-step response of the measured AEs to electron cyclotron heating (ECH) power is seen. In a first step, the continuous character of the unstable AEs cha

Plasma breakdown using electron cyclotron waves with toroidally inclined launch has been studied experimentally in the stellarator/heliotron device, Heliotron J. The experimental results show that the second harmonic X-mode breakdown has a weak depen
