Reevaluation of the Braginskii viscous force for toroidal plasma

Deep electric field predictions by drift-reduced Braginskii theory with plasma-neutral interactions based upon experimental images of boundary turbulence

We present 2-dimensional turbulent electric field calculations via physics-informed deep learning consistent with (i) drift-reduced Braginskii theory under the framework of an axisymmetric fusion plasma with purely toroidal field and (ii) experimental estimates of the fluctuating electron density and temperature on open field lines obtained from analysis of gas puff imaging of a discharge on the Alcator C-Mod tokamak. The inclusion of effects from the locally puffed atomic helium on particle and energy sources within the reduced plasma turbulence model are found to strengthen correlations betw…

重新评估兆电子伏离子在聚变等离子体中的影响：基于回旋动理学模拟

Reassessing the impact of megaelectronvolt ions in fusion plasmas via gyrokinetic simulations

通过回旋动理学模拟重新评估兆电子伏离子对聚变等离子体湍流抑制的影响，指出Mazzi等人结果因模拟分辨率不足而失真，修正后热导率显著增加，质疑其性能增强结论。
