The ASDEX Upgrade advanced tokamak scenario with central q close to 1 has been reproduced on JET. For almost identical q profiles, the comparative analysis does show similar features like the fishbone activity and the current profile evolution. In JET, transport analyses indicates that an internal transport barrier (ITB) has been produced. Gradient length criterions based on the ion temperature gradient turbulence stabilization are used to characterize the ITBs in both devices. The trigger of ITBs is associated with rational surfaces in both devices although the underlying physics for this triggering seems different. This experiment has the prospect to get closer to identity experiments between the two tokamaks.

ASDEX Upgradeの先進トカマクシナリオにおいて、中心qが1に近い状態がJETで再現された。ほぼ同一のq分布に対して、比較解析はフィッシュボーン活動や電流分布の時間発展などの類似した特徴を示している。JETでは、輸送解析により内部輸送障壁(ITB)が形成されたことが示されている。イオン温度勾配乱流の安定化に基づく勾配長の判定基準が、両装置におけるITBを特徴付けるために用いられている。ITBのトリガーは両装置とも有理面と関連しているが、その背後にある物理機構は異なっているようである。本実験は、両トカマク間のアイデンティティ実験に近づく可能性を有している。
