回顾了2014-2016年JET的研究成果，分析了其对优化ITER主动和非主动运行研究计划的意义。自2011年安装以来，ITER第一批壁材成功进行了60多个小时的等离子体运行。用第一性原理模型支持了I-ELM型分流器能量通量密度的多机缩放。利用模拟ITER装置的一组三个干扰缓解阀，报告了ITER相关的干扰实验和第一原理建模。给出了氘和氢的L-H功率阈值的见解，强调了磁结构的重要性和最近在边缘径向电中的精细尺度结构的测量。核心和基座限制的无因次扫描提供了新的信息，以阐明第一壁材料对融合性能的重要性。在ITER三角度下，H模等离子体(在β （N)接近1.8时H = 1，在N / N （GW）接近0.6时）在2毫安下持续5秒。ITER中子码已在高性能实验中得到验证。对即将到来的D-T运动和14mev中子校准策略进行了展望。
The 2014-2016 JET results are reviewed in the light of their significance for optimising the ITER research plan for the active and non-active operation. More than 60 h of plasma operation with ITER first wall materials successfully took place since its installation in 2011. New multi-machine scaling of the type I-ELM divertor energy flux density to ITER is supported by first principle modelling. ITER relevant disruption experiments and first principle modelling are reported with a set of three disruption mitigation valves mimicking the ITER setup. Insights of the L-H power threshold in Deuterium and Hydrogen are given, stressing the importance of the magnetic configurations and the recent measurements of fine-scale structures in the edge radial electric. Dimensionless scans of the core and pedestal confinement provide new information to elucidate the importance of the first wall material on the fusion performance. H-mode plasmas at ITER triangularity (H = 1 at beta(N) similar to 1.8 and n/n(GW) similar to 0.6) have been sustained at 2 MA during 5 s. The ITER neutronics codes have been validated on high performance experiments. Prospects for the coming D-T campaign and 14 MeV neutron calibration strategy are reviewed.
