Practical material to use in tokamak

In summary, the use of buckminsterfullerene or bucky balls may not have a significant impact on the practicality of using them in a tokamak due to the plasma being confined by a magnetic field rather than in direct contact with the material. However, they may offer more resistance to damage. Alternatively, a magnetically confined liquid could be a better solution for this purpose. More information on this can be found at http://www.pppl.gov/projects/pages/cdxu.html [Broken].

could the use of buckminsterfullerene or bucky balls be a more practical material to use in tokamak because of the less friction it would create on the plasma?

Probably wouldn't make much difference. Since the plasma is not in contact with the material, but is confined by a magnetic field, the drag coeficient of the construction material is not much of a concern. Buckyballs would be more resistant to damage, but I think the idea of a magnetically confined liquid would be better for that purpose.

There is some information about that at http://www.pppl.gov/projects/pages/cdxu.html [Broken] if you look in the middle of the page.

1. What materials are commonly used in tokamaks?

The most commonly used materials in tokamaks are a combination of metals, such as tungsten, molybdenum, and stainless steel, and ceramics, including beryllium and silicon carbide. These materials are chosen for their high melting points, low vapor pressures, and ability to withstand high heat and radiation.

2. How are these materials tested for use in tokamaks?

Before being used in a tokamak, materials must undergo extensive testing to ensure their compatibility with the extreme conditions inside the device. This includes testing for their ability to withstand high temperatures, radiation, and plasma interactions, as well as their mechanical properties and potential for erosion or damage.

3. What challenges are faced in finding suitable materials for tokamaks?

One of the major challenges in finding materials for tokamaks is that they must be able to withstand the intense heat and radiation produced by the plasma, while also being compatible with the cooling systems and other components of the device. Additionally, materials must be able to withstand the constant bombardment of high-energy particles without degrading or releasing impurities into the plasma.

4. Are there any new materials being developed for use in tokamaks?

Scientists and engineers are constantly researching and developing new materials that could potentially be used in tokamaks. Some promising materials include advanced ceramics, such as carbon composites and liquid metals, which have the potential to withstand even higher temperatures and radiation levels than current materials.

5. How do these materials contribute to the overall success of a tokamak?

The materials used in a tokamak are crucial to its success, as they directly impact its ability to produce and sustain a stable plasma and achieve fusion reactions. By withstanding the extreme conditions inside the device, these materials contribute to the overall efficiency and safety of the tokamak, making it a viable option for future energy production.
