在大型螺旋装置 [O.本岛等人，物理学。等离子 6, 1843 (1999)]。当这种现象发生时，核心区域的电子热扩散率突然降低，而不会改变感兴趣区域的局部参数。因此，这种现象可以被视为迄今为止仅在许多托卡马克中观察到的所谓“非局域”电子温度升高。
The first observation of a significant rise of core electron temperature in response to edge cooling in a helical plasma has been made on the Large Helical Device [O. Motojima et al., Phys. Plasmas 6, 1843 (1999)]. When the phenomenon occurs, the electron heat diffusivity in the core region is reduced abruptly without changing local parameters in the region of interest. Therefore the phenomenon can be regarded as a so-called “nonlocal” electron temperature rise observed so far only in many tokamaks.
