Progress in physics understanding and theoretical model development of plasma transport and confinement in the ITPA Transport and Confinement Topical Group since the publication of the ITER Physics Basis was summarized focusing on the contributions to ITER and burning plasma prediction and control. This paper provides a general and streamlined overview on the advances that were mainly led by the ITPA TC joint experiments and joint activities for the last 15 years. This paper starts with the scientific strategy and scope of the ITPA TC Topical group and overall picture of the major progress, followed by the progress of each research field: particle transport, impurity transport, ion and electron thermal turbulent transport, momentum transport, impact of 3D magnetic fields on transport, confinement mode transitions, global confinement, and reduced transport modeling.

This conference report summarizes the contributions to, and discussions at, the 21st Joint EU-US Transport Task Force Workshop, held in Leysin, Switzerland, during 5-8 September 2016. The workshop was organized under 8 topics: progress towards full-F kinetic turbulence simulation; high and low Z impurity transport, control and effects on plasma confinement; 3D effects on core and edge transport (including MHD, external fields and stellarators); predictive experimental design; electron heat transport and multi-scale integration; understanding power decay length in the Scrape-Off Layer (SOL); role of the SOL in the L-H transition; validation of fundamental turbulence properties against turbulence measurements.

Effects of plasma size and kinetic electron response on momentum transport

Idomura, Yasuhiro; Jolliet, S.; Camenen, Y.*

no journal, , 

Linear analyzes ITG-TEM turbulence are performed by developing a kinetic electron model in a global gyrokinetic full-f Vlasov code GT5D. Through comparisons with a local flux-tube gyrokinetic code GKW, it is found that finite plasma size effects provide changes in mode structures leading to generation of residual stress. It is also shown that the residual stress changes its sign in each parameter regime where ITG modes or TEM modes are dominant. The result shows that plasma rotation driven by the residual stress may change its direction depending on the dominant modes.
