将在ITER上安装一个工作频率为170 GHz、脉冲长度为3600 s的24 MW电子回旋加速器系统。EC电厂应向等离子体输送20 MW的该功率，用于加热和电流驱动（H&CD）应用。EC系统被设计用于等离子体的平顶阶段中的等离子体引发、集中加热、电流驱动、电流分布剪裁和磁流体动力学控制（特别是锯齿和新古典撕裂模式）。2012年进行了初步设计审查，确定需要将EC系统扩展应用于ITER等离子体脉冲的等离子体斜升、平顶和斜降阶段。根据这些应用程序确定各种功能的优先次序，与其他H&CD系统相比，EC系统可以唯一地解决这些应用程序。已经开发了一个初始尝试，以优先考虑所分配的H&CD应用程序的三个设想的场景：ELMy H模式（15 MA），混合（12 MA），和高级（19 MA）的情况下。这导致了...
A 24 MW Electron Cyclotron (EC) system operating at 170 GHz and 3600 s pulse length is to be installed on ITER. The EC plant shall deliver 20 MW of this power to the plasma for Heating and Current Drive (H&CD) applications. The EC system is designed for plasma initiation, central heating, current drive, current profile tailoring, and Magneto-hydrodynamic control (in particular, sawteeth and Neo-classical Tearing Mode) in the flat-top phase of the plasma. A preliminary design review was performed in 2012, which identified a need for extended application of the EC system to the plasma ramp-up, flattop, and ramp down phases of ITER plasma pulse. The various functionalities are prioritized based on those applications, which can be uniquely addressed with the EC system in contrast to other H&CD systems. An initial attempt has been developed at prioritizing the allocated H&CD applications for the three scenarios envisioned: ELMy H-mode (15 MA), Hybrid (∼12 MA), and Advanced (∼9 MA) scenarios. This leads to the ...
