Measurements of charge transfer cross sections of fusion-related high-Z impurities and database construction

在0.5 ~ 32 keV的能量范围内，获得了钨、镍、铁、硼和铍的单、双电荷离子与气体靶碰撞的单、双电子俘获截面的绝对值。所研究的目标气体为惰性气体氦、氖、氩、氪和分子气体氢、碳、二氧化碳、氮、甲烷、乙烷、丙烷。部分研究结果已于2006年发表在Journal of Plasma and Fusion Research上，另一部分已于2008年3月提交给Journal of Chemical Physics。我们正在准备另外两篇论文，并于2006年9月建立了电荷转移截面实验数据库，并向公众开放。目前，该系统已收录了486个碰撞系统的1766条截面记录，并对2004年、2005年和2006年发表的论文进行了整理和评述（原子和分子数据及其应用国际会议; 2006年10月，ER-JP/JP-KR联合讲习班; 2007年2月，光子，电子和原子碰撞国际会议; 2007年7月，核心大学计划研讨会; 2007年11月），与国际原子能机构代表达成协议，建立一个网络搜索界面，进入国际原子能机构Genie网络中的数据库（一个通用的互联网搜索引擎的原子数据）。M.今井将于2008年6月飞往维也纳，就“聚变相关材料的最新电荷转移截面测量”提供咨询意见，介绍这些结果，并制定在吉尼建造接口的计划。

Absolute values for single and double electron capture cress sections for singly and doubly charged ions of tungsten, nickel, iron, boron and beryllium colliding with gaseous targets have been obtained at 0.5 to 32 keV. The target gases studied were inert gases of helium, neon, argon and krypton and molecular gases of hydrogen, carbon incur: rode, carbon dioxide, nitrogen, methane, ethane and propane. Apart of the results has been published in the Journal of Plasma and Fusion Research in 2006 and another part was submitted to the Journal of Chemical Physics in March, 2008. We are preparing two more articles to submit in fixture.A database for experimental charge transfer cross sections has been constructed and opened to public since September, 2006. In the present, it provides 1766 records of cross sections about 486 collision systems with bibliographic data and comments, compiled from papers published in 2004, 2005 and 2006.These outcomes were presented in 4 international conferences or workshops (International Conference on Atomic and Molecular Data and Their Applications ; October 2006, ER-JP/JP-KR Joint Workshop ; February 2007, International Conference on Photonic, Electronic and Atomic Collisions ; July 2007, Core University Program Workshop ; November 2007), where an agreement was made with IAEA representative to build a web search interface to our database in the IAEA Genie network (a GENeral Internet search Engine for atomic data). M. Imai will fly to Vienna in June, 2008 to provide consultants' advice on 'recent charge transfer cross section measurements for fusion related materials' presenting these outcomes and formulating a plan for construction of the interface in Genie.
