| Outline of Final Research Achievements |
To understand the fundamental atomic processes in the fusion plasma, especially in low temperature plasma around the diverter wall, the measurements for an interaction between low energy electron and metal surface has been started. The experiment has been performed by extending to the surface target from an electron spectroscopy of gas phases. In this project, we set the ultra-high vacuum system, checked the operation using the gas targets comparing the previous results, and set the rotational system of the surface target at the interaction region. We also calculated the atomic factor, which is important to understand the scattering from the surface with the collaborator in Spain. Now we just start to measure the angular distributions from Tungsten metal surface by electron impact. It is expected that the comparison of scattering processes between metal surface and single atom would be performed soon.
