JSPS-NRF-NSFC A3 foresight program seminar. Proceedings of Japan-China joint seminar on atomic and molecular processes in plasma

As one of the activities of JSPS-NRF-NSFC A3 Foresight Program in the field of Plasma Physics (NSFC: No.11261140328), Japan-China Joint Seminar on Atomic and Molecular Processes in Plasma was held on July 30 - August 4, 2012, in Lanzhou, China. The total number of the officially registered participants was 37, in which 14 from Japan, 21 from China, 1 from Germany, and 1 from Ireland. This seminar is the extension of the last three seminars that were held on March 6-11, 2004 in Lanzhou, China, on October 6-12, 2007 in Dunhuang, China, and on October 26-31, 2009 in Xi'an, China. In the nuclear fusion plasma, there are quite a variety of atomic processes such as ionization, excitation, di-electronic recombination, collisional electron transfer, cascade radiation, and cascade Auger decay over the wide range of plasma temperature. The knowledge of those processes is indispensable for the evaluation and improvement of the plasma properties. Especially, in these years, the property of tungsten ions has become a subject of urgent investigations since tungsten has been considered as one of the plasma facing wall materials. Because of the diversity of the subject, it is desirable to investigate them by international collaboration groups. The present seminar may contribute to realize the above stated aim; especially it has given an opportunity for the collaborative workers to illustrate their achievements. The present seminar summarizes the collaborative researches for the last decade and proposes the issues for the future prospect. This issue is the collection of 19 papers presented at the entitled meeting. All the 19 of the presented papers are indexed individually. (J.P.N.)
