降低面向等离子体部件的热负荷是下一代聚变堆（如ITER）实现长脉冲或稳态运行的关键问题之一。因此，研究等离子体复合过程中分离等离子体的基本性质和结构，对于减少偏滤器板的热量和粒子通量具有重要意义。我们在偏滤器等离子体模拟器NAGDIS-Ⅱ装置上进行了等离子体分离的基础实验。我们已经观察到电子离子复合（EIR），其中包括三体和辐射复合，和分子激活复合（MAR）在NAGDIS-II。（orig.）参考文献9。
Heat load reduction to plasma-facing components is one of the most crucial issues for the next generation fusion reactors such as ITER, which will realize a long pulse or a steady state operation. For the reason mentioned above, it is quite important to investigate fundamental property and structure of detached plasmas associated with plasma recombinations, which can decrease heat and particle flux to the divertor plate. We have done basic experiments on the plasma detachment in the divertor plasma simulator, NAGDIS-II device. We have observed both electron-ion recombination (EIR), which includes three-body and radiative recombinations, and molecular activated recombination (MAR) in NAGDIS-II. (orig.) 9 refs.
