A series of experiments have been carried out in 2008 at JT-60U and JET to find common characteristics and explain differences between internal transport barriers (ITBs). The identity experiments succeeded in matching the profiles of most dimensionless parameters at the time ITBs were triggered. Thereafter the q-profile development deviated due to differences in non-inductive current density profile, affecting the ITB. Furthermore, the ITBs in JET were more strongly influenced by the H-mode pedestal or edge localized modes. It was found to be difficult to match the plasma rotation characteristics in both devices. However, the wide range of Mach numbers obtained in these experiments shows that the rotation has little effect on the triggering of ITBs in plasmas with reversed magnetic shear. On the other hand the toroidal rotation and more specifically the rotational shear had an impact on the subsequent growth and allowed the formation of strong ITBs.

2008年にJT-60UおよびJETにおいて、内部輸送障壁(ITB)の共通特性を特定し、その差異を説明するために一連の実験が実施された。同一条件実験(identity experiments)では、ITBが発生した時点でのほとんどの無次元パラメータの一致に成功した。その後、非誘導電流密度分布の差異によりq分布の時間発展に相違が生じ、それがITBに影響を及ぼした。さらに、JETにおけるITBはHモードペデスタルまたは周辺局在モード(ELM)の影響をより強く受けた。両装置においてプラズマ回転特性を一致させることは困難であることが判明した。しかしながら、これらの実験で得られた広範囲のマッハ数は、逆磁気シアを有するプラズマにおけるITBの発生に対して回転が及ぼす影響が小さいことを示している。一方で、トロイダル回転、より具体的には回転シアは、その後のITBの成長に影響を及ぼし、強いITBの形成を可能にした。
