Since 1992, the boronization using B10H14 (decaborane-based boronization) has been utilized in JT-60 once or twice a year. It is very effective in reducing both the impurities, like oxygen and carbon, in the plasma and in recycling fuel particles. Ho

Spectroscopy of ion-induced secondary electrons emitted from single crystals allows observation of high-energy shadowing which is the initial stage of ion channeling. The high-energy shadowing effect is sensitive to short-range (∼ 0.1 A) screening
