采用全无感低混合电流驱动（LHCD），在TRIAM-1M上成功实现了超过5h的放电。利用量热法研究了5h放电过程中面向等离子体组件（pfc）的热负荷分布，估计注入的射频（RF）功率与pfc的总热负荷相吻合。同时研究了快速电子的直接损失功率和电荷交换（CX）过程引起的热流密度的功率平衡。
A discharge longer than 5h was successfully achieved on TRIAM-1M by fully non-inductive lower hybrid current drive (LHCD). The heat load distribution into the plasma facing components (PFCs) during the 5h discharge was investigated using calorimetric measurements, which estimated that the injected radio frequency (RF) power coincided with the total heat load amount to the PFCs. The power balance, including the portion of direct loss power of the fast electrons and the heat flux due to the charge exchange (CX) process, was also investigated.
