Review of D - T Experiments Relevant to Burning Plasma

Progress in the performance of tokamak devices has enabled not only the production of significant bursts of fusion energy from deuterium-tritium (D-T) plasmas in the Tokamak Fusion Test Reactor (TFTR) and the Joint European Torus (JET) but, more importantly, the initial study of the physics of burning magnetically confined plasmas. TFTR and JET, in conjunction with the worldwide fusion effort, ...

Uc - 427 Ity Analysis of Toroidicity - Induced Alfven Eigenmodes in Tftr Dt Experiments

The toroidicity-induced Alfv6n eigenmodes (TAE) with radially extended structure are found to be stable in the Tokamak Fusion Test Reactor Deuterium-Tritium plasmas. A core localized TAE mode is shown to exist near the center of the plasma at small magnetic shear and finite plasma beta, which can be destabilized by energetic alpha particles on TFTR. With additional instability drive from fast m...

Alpha Particle Induced Magnetoacoustic Instability in a Thermonuclear Plasma

We show that in a thermonuclear plasma the magnetosonic wave propagating normal to the magnetic field can be unstable. The growth rate is small, however, and the wave is easily stabilized by perpendicular thermal conduction. IN A FULLY IGNITED thermonuclear plasma the fusion energy production balances the various energy losses and the fusion reaction is self-sustaining. The product ions (alpha ...

Fusion: the way ahead

• Fusion is the process whereby two light nuclei bind to form a heavier nucleus with the release of energy • Harnessing fusion on Earth via deuterium and tritium reactions would lead to an environmentally friendly and almost limitless energy source • One promising route to fusion power is to magnetically confine a hot, dense plasma inside a doughnut-shaped device called a tokamak • The JET toka...
