Phys. Rev. Lett. 76, 2286–2289 (1996)First Evidence of Collective Alpha Particle Effect on Toroidal Alfvén Eigenmodes in the TFTR D-T ExperimentReceived 29 June 1995; published in the issue dated 25 March 1996 The alpha particle effect on the excitation of toroidal Alfvén eigenmodes (TAE) was investigated in deuterium-titrium (D-T) plasmas in the Tokamak Fusion Test Reactor. rf power was used to position the plasma near the instability threshold, and the alpha particle effect was inferred from the reduction of rf power threshold for TAE instability in D-T plasmas. Initial calculations indicate that the alpha particles contribute 10%–30% of the total drive in a D-T plasma with 3 MW of peak fusion power. © 1996 The American Physical Society URL:
