[1N18] Radial distribution of hydrogen atoms from RF discharge tube

*Shintaro Nakano1, Daisuke Yuki1, Ikuji Takagi1 (1. Kyoto Univ.)

Keywords:Fusion reactor material, Hydrogen atom, Reflection, RF discharge tube

For long term operation of fusion plasma, it is necessary to know the characteristics of hydrogen reflection on solid surface.
As a preliminary experiment of low energy reflection, we measured radial distribution of hydrogen atoms from RF plasma source by use of a permeation probe.
