Ion cyclotron resonance heating experiments have been carried out in reactor relevant scenarios during the deuterium-tritium (DTE1) campaign in JET. For the first time it was possible to assess the scheme with a deuterium minority in tritium plasmas: this produced a steady state DT fusion power of up to 1.66 MW for input ICRF power of 6 MW. Strong ion heating, with a core ion temperature of up to 13 keV, was observed when using 3He minority heating in both 50:50 DT and tritium dominated H mode plasmas. Second harmonic tritium heating was also studied and, as expected for JET plasma conditions, produced mainly electron heating. Finally, the `inverted' scenario of tritium minority in deuterium was successfully demonstrated.
离子回旋共振加热实验已在JET的氘-氚（DTE1）运动期间于反应堆相关场景中开展。首次得以评估在氚等离子体中采用氘少数成分的方案：该方案在6 MW输入ICRF功率下产生了高达1.66 MW的稳态DT聚变功率。在50:50 DT及氚主导的H模等离子体中，使用3He少数成分加热时观察到强离子加热，芯部离子温度高达13 keV。还研究了二次谐波氚加热，正如JET等离子体条件所预期，该加热主要产生电子加热。最后，成功演示了氚为少数成分、氘为多数成分的“反转”方案。
