DIII-D团队在燃烧等离子体场景、高聚变性能稳态场景和基础托克马克物理学的开发方面取得了重大进展。类似于ITER基线方案的放电表明，在静止条件下，归一化融合性能比ITER参考方案中Q = 10的指定值高出近50%。DIII-D还演示了在静止条件下的放电，其性能增强，在ITER中以降低的电流投射到Q ~ 10超过1小时，如果这种操作模式可以在ITER中实现的话。已获得具有全无感操作的高融合性能的证明。这项工作的基础是验证约束外推，中断避免和缓解，氚保留，边缘局部模式避免和操作以上的无壁压力限制的方法的研究。此外，DIII-D设施的独特能力还以前所未有的时间和空间分辨率推进了对锯齿不稳定性、电子热传输阈值行为、无外扭矩情况下等离子体旋转、边缘基座区域测量的研究。等离子体燃料。在基础水平上理解这些现象有助于托卡马克方案的开发和最终优化。
Significant progress in the development of burning plasma scenarios, steady-state scenarios at high fusion performance and basic tokamak physics has been made by the DIII-D team. Discharges similar to the ITER baseline scenario have demonstrated normalized fusion performance nearly 50% higher than the value specified for Q = 10 in ITER reference scenario, under stationary conditions. Discharges have also been demonstrated in DIII-D with enhanced performance under stationary conditions that project to Q ~ 10 for longer than 1 h in ITER at reduced current, if such a mode of operation can be realized in ITER. Proof of high fusion performance with full noninductive operation has been obtained. Underlying this work are studies validating approaches to confinement extrapolation, disruption avoidance and mitigation, tritium retention, edge localized mode avoidance and operation above the no-wall pressure limit. In addition, the unique capabilities of the DIII-D facility have advanced studies of the sawtooth instability with unprecedented time and space resolution, threshold behaviour in the electron heat transport, rotation in plasmas in the absence of external torque, measurements in the edge pedestal region and plasma fuelling. Understanding these phenomena at a fundamental level contributes to development and ultimately the optimization of tokamak scenarios.
