论文摘要
自然稳定榆树，并且具有比Eped预测大的宽度，因为I模式基座并不受MHD不稳定性“限制”，因此，I模型是研究漂移微生物含量在基座中的作用的绝佳实验室。我们在这里介绍了一项基于陀螺仪模拟（使用基因）的研究，以模拟C模式中I模式基座中的波动和热传输。我们发现在C模式上观察到的弱相干模式是静电离子温度梯度/杂质密度梯度（ITG/杂质）驱动模式。 ITG/杂质模式匹配频率和在I模式上观察到的杂质限制时间。非线性ETG模拟，可以在实验误差栏中符合实验热通量与轮廓调节的匹配。模拟，不同的杂质水平（ZEFF）以及温度和密度曲线（在实验误差栏内），用于探测波动和运输的敏感性。
Naturally stable to ELMs, and with widths larger than EPED predictions, the I-modes are an excellent laboratory for investigating the role of drift micro-instabilities in pedestals since I-mode pedestal are not "limited" by MHD instabilities. We present here a study based on gyrokinetic simulations (using GENE) to model fluctuations and heat transport in the I-mode pedestals in C-Mod. We find the Weakly Coherent Mode observed on C-Mod I-mode to be an electrostatic Ion Temperature Gradient/Impurity density gradient (ITG/Impurity) driven mode. The ITG/Impurity mode match frequency and the impurity confinement time observed on the I-mode. Nonlinear ETG simulations, can match experimental heat flux with profile adjustment well within experimental error bars. Simulations, varying impurity level (Zeff) and temperature and density profiles (within experimental error bars), are used to probe the sensitivity of fluctuations and transport.
