Purpose of the Meeting

The goal of the Transport Working Group is to work together on understanding of the basic mechanisms responsible for particle, momentum and energy transports in magnetic confinement plasmas, and ultimately, controlling of the transport processes. It is important parts of the task to characterize the specific features of the transport phenomena, such as non-locality and non-diffusivity, and their correlations with the spatial and temporal features of fluctuations in core and edge regions of the plasmas. The 3D effects on transport, which are important and common in toroidal plasmas, are also emphasized in this meeting.

Working group of the Meeting

In order to realize the purpose described above and keep continuity, five topical foci were identified for the initial working group. These are:

a) Momentum transport
b) Non-locality in transport
c) Edge turbulence and L-H transition
d) 3D effects on transport

e) Particle, momentum and heat pinches

Background of the Meeting

The Transport Task Force started during 1988-89 in the United State has fostered and guided works on plasma turbulence and transport for more than twenty years. In 1994, the European fusion community created a similar task force which was inspired by the U.S. organization. In alternate years, the meetings of the US and EU TTFs are held jointly and every effort is made to foster collaborations between the research groups represented.
Based on the significant development of research activities on plasma transport and turbulence in the Asia-Pacific region, a formation of an Asia Pacific Transport Working Group along the lines of the US-EU Transport Task Force was discussed on  October 15, 2010 during the IAEA FEC conference, Daejeon, Korea. Present at the meeting were K. Ida, NIFS; M. Yagi, Kyushu-Univ./JAEA; L.W. Yan and J.Q. Dong, SWIP; X. Gao, ASIPP; J. Y. Kim, NFRI; T. S. Hahm, SNU and PPPL; Y. S. Na, SNU; Liu Chen, IFTS, Zhejiang Univ. and UCI; P. H. Diamond, NFRI and UCSD. Profs. Diamond and Chen acted as advisors.

The 1st Asia Pacific Transport Working Group (APTWG) International Conference was held from June 14 to June 17, 2011, at the National Institute for Fusion Science (NIFS), Japan, with a great success. It was decided at the Conference that the 2^nd Asia Pacific Transport Working Group (APTWG) International Conference be held at Chengdu, China, in 2012.
