What material is used for tokamak?
What material is used for tokamak?
Molybdenum is used for the first wall material in Alcator C-Mod (1991). Liquid lithium (LL) was used to coat the PFC of the Tokamak Fusion Test Reactor in the Lithium Tokamak Experiment (TFTR, 1996).
What is a divertor in a fusion reactor?
The divertor is a component of large MFE (Magnetic Fusion Energy) experiments which remove heat and helium ash from the plasma. Divertors are typically made of tungsten or carbon or other materials that have a high melting temperature. Currently, there are three main divertor technologies under development.
How does a divertor work in fusion?
Situated at the bottom of the vacuum vessel, the divertor extracts heat and ash produced by the fusion reaction, minimizes plasma contamination, and protects the surrounding walls from thermal and neutronic loads.
Who funds ITER?
ITER is funded and run by seven member parties: China, the European Union, India, Japan, Russia, South Korea and the United States.
How does a tokamak heat plasma?
Within the tokamak, the changing magnetic fields that are used to control the plasma produce a heating effect. The magnetic fields create a high-intensity electrical current through induction, and as this current travels through the plasma, electrons and ions become energized and collide.
When was tokamak introduced?
1958
The first tokamak, T-1, began operation in Russia in 1958. Subsequent advances led to the construction of the Tokamak Fusion Test Reactor at Princeton Plasma Physics Laboratory and Joint European Torus in England, both of which achieved record fusion power in the 1990s.
Is India member of ITER?
As signatories to the ITER Agreement, the ITER Members China, the European Union, India, Japan, Korea, Russia and the United States will share in the cost of project construction, operation and decommissioning, and also share in the experimental results and any intellectual property generated by the project.
