Deep electric field predictions by drift-reduced Braginskii theory with plasma-neutral interactions based upon experimental images of boundary turbulence. (arXiv:2204.11689v1 [physics.plasm-ph] CROSS LISTED)

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 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 …
