| Abstract Scope |
Plasma-facing components (PFCs) are required to have specialized properties such as low activation, low sputter erosion, low tritium retention, and high melting point. They must be able to function at high temperatures for extended periods of time whilst being bombarded with Tritium and Deuterium. Tungsten (W) is one of the leading candidates for PFCs inside of the divertor for its ability to match the requirements, such as its high melting temperature and low tritium retention. This is unfortunately paired with W having a very brittle nature. To this end, guided by the work done by Gonzalez and Oriani a custom-designed differential pressure and temperature vessel is utilized along with custom-made tungsten discs to evaluate flux of deuterium through the Tungsten. The main driving factor for this is believed to be the Soret effect characterized by a negative heat of transport. We demonstrate functionality of the experiment in this discussion. |
