  1. Production and Compilation ofCharge Changing Cross Sections ofIon-Atom and Ion-Molecule CollisionsMakoto Imaiimai@nucleng.kyoto-u.ac.jpDepartment of Nuclear Engineering, Kyoto University京都大学 原子核工学専攻今井 誠 KR-JP/JP-KR Joint Workshop, KAERI, Daejeon, Feb 1, 2007

  2. Outline • Compilation of experimental charge changing cross sections from literature(co-operative activity between JAEA and Kyoto Univ.) • Compilation since 1983 • Electric version (prototype) started in 2006http://toshi3.nucleng.kyoto-u.ac.jp:5560/isqlplus/ • Production (measurements) of charge changing (e-capture) cross sections of some fusion-related collision systemsat Kyoto Univ.Be1,2+, B1,2+, C1,2,3+, Cr1,2+, Fe+, Ni1,2+, W+ + He, Ne, Ar, Kr, H2, CO, CO2, N2, CH4, C2H6, C3H8

  3. Compilation of Experimental Charge Changing Cross Sections • Number of Collected Papers • Journals under the survey Atomic Data and Nuclear Data Tables The European Physical Journal D Europhysics Letters JETP JETP Letters Journal of Physical and Chemical Reference Data Journal of the Physical Society of Japan Journal of Physics B: Atomic, Molecular and Optical Physics Nuclear Instruments and Methods in Physics Research sect.

W will be used as DIVERTOR Buffle and Dome in the ITER! IAEA Coordinated Research Project (CRP) on “Atomic Data for Heavy Element Impurities” (2005 – 2009) requires data for elements with atomic mass ≥ 13; (Ar, Kr, Xe), Si, Cl, Cr, Fe, Ni, Cu, Mo and W!
