Surface analysis of lithium-6 ($$^{6}$$Li) was performed for both 95 % and 40 % $$^{6}$$Li-enriched lithium titanate (Li$$_{2}$$TiO$$_{3}$$) samples as the candidate tritium breeding material using 2.6 MeV-proton Rutherford Backscattering Spectroscopy (RBS). The depth resolution of this method was enough to measure the $$^{6}$$Li depth profile in terms of the evaluation of thermal neutron transportation. The atomic density of $$^{6}$$Li could be measured within the error of 27 % for both samples although the accuracy of 5 % was not achieved for the evaluation of tritium breeding. It was confirmed that the sample atomic compositions agreed with Li$$_{2}$$TiO$$_{3}$$ within errors of 30 % for Li/Ti and 15 % for O/Ti. The whole errors were caused by the data accuracy of scattering cross sections predominately. Providing more accurate cross section data can lead to the utilization of the RBS method for tritium breeding materials analysis.

For Broader Approach Activities, which are joint project between Japan and Europe, JAEA who is the Japanese implementing Agency, has established "International Fusion Energy Research Centre (IFERC)" in Rokkasho, Aomori Japan. At research facilities in IFERC, DEMO R&D Building and CSC&REC Building, in which research and development activities are carried out, experimental equipment and components had been installed and in operation until the end of 2011. The outline of those facilities are described in a poster.
