综述了JET ICRH和LHCD系统的最新进展。反馈控制减轻了等离子体天线耦合的传统困难。高等离子体性能的实验结果，基本约束方面和相关的下一代托卡马克的问题进行了说明。ICRH允许一个狭窄的功率沉积分布将被定位在独立于等离子体密度和大小。作者证明，在大型托卡马克，使用少数物种的约束可以被删除，并提出了在ITER中以ω = ω CD加热平衡的D/T混合物。LHCD允许获得最高的电流效率。根据JET结果讨论了波可达性的条件。LHCD非常适合在电流上升阶段节省伏秒。所观察到的协同LHCD/ICRH加速快电子是一个有前途的路线更高的电流驱动效率，但提出了未解决的物理方面进行了分析。他们最后考虑了稳态聚变反应堆的前景。
The latest developments of the JET ICRH and LHCD systems are reviewed. Feedback controls have alleviated the traditional difficulties with plasma-antenna coupling. Experimental results on high plasma performance, basic confinement aspects and issues relevant to the next generation of tokamaks are described. ICRH allows a narrow power deposition profile to be localised at will independently of the plasma density and size. The authors demonstrate that in large tokamaks, the constraint to use a minority species can be removed and heating a balanced D/T mixture at omega = omega CD in ITER is proposed. LHCD allows the highest current efficiency to be obtained. The conditions for wave accessibility are discussed in light of the JET results. LHCD is well adapted to save volt seconds in the current rise phase. The observed synergistic LHCD/ICRH acceleration of fast electrons is a promising route towards higher current drive efficiency but raises unresolved physics aspects which are analysed. They finally consider the prospects of a steady state fusion reactor.
