Probe measurements of plasma fluctuations in the divertor region of ASDEX Upgrade reveal the existence of two quiescent regions close to the separatrix: one on the low field side scrape-off layer and one on the high field side of the private flux region. The X-point manipulator at ASDEX Upgrade provides the unique possibility of obtaining continuous measurements of the ion-saturation current from the low field side scrape-off layer through the private flux region and into the high field side scrape-off layer.

ASDEX 升级中 X 点以下的静止区域

对 ASDEX Upgrade 偏滤器区域中等离子体波动的探测测量揭示了靠近分离面的两个静止区域的存在：一个位于低场侧刮削层，另一个位于私有通量区域的高场侧。ASDEX 升级中的 X 点操纵器提供了独特的可能性，可以连续测量从低场侧刮除层通过私有通量区域进入高场侧刮除层的离子饱和电流。
