Deep electric field predictions by drift-reduced Braginskii theory with plasma-neutral interactions based upon experimental images of boundary turbulence
Abhilash Mathews, Jerry Hughes, James Terry +1
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 axis…
Deep modelling of plasma and neutral fluctuations from gas puff turbulence imaging
A. Mathews, J. L. Terry, S. G. Baek +8
The role of turbulence in setting boundary plasma conditions is presently a key uncertainty in projecting to fusion energy reactors. To robustly diagnose edge turbulence, we develo…
Tracking Blobs in the Turbulent Edge Plasma of a Tokamak Fusion Device
Woonghee Han, Randall A. Pietersen, Rafael Villamor-Lora +7
The analysis of turbulence in plasmas is fundamental in fusion research. Despite extensive progress in theoretical modeling in the past 15 years, we still lack a complete and consi…
Comparison between mirror Langmuir probe and gas puff imaging measurements of intermittent fluctuations in the Alcator C-Mod scrape-off layer
R. Kube, A. Theodorsen, O. E. Garcia +3
Statistical properties of the scrape-off layer (SOL) plasma fluctuations are studied in ohmically heated plasmas in the Alcator C-Mod tokamak. For the first time, plasma fluctuatio…
Universality of Poisson-driven plasma fluctuations in the Alcator C-Mod scrape-off layer
A. Theodorsen, O. E. Garcia, R. Kube +2
Large-amplitude, intermittent fluctuations are ubiquitous in the boundary region of magnetically confined plasmas and lead to detrimental plasma-wall interactions in the next-gener…
Characterization of SOL Plasma Flows and Potentials in Alcator C-Mod
R. Hong, S. J. Wukitch, Y. Lin +4
Gas-puff imaging techniques are employed to determine the far SOL region radial electric field and the plasma potential in ICRF heated discharges in the Alcator C-Mod tokamak. The…
Gyrokinetic projection of the divertor heat-flux width from present tokamaks to ITER
C. S. Chang, S. Ku, A. Loarte +11
The XGC1 edge gyrokinetic code is used for a high fidelity prediction for the width of the heat-flux to divertor plates in attached plasma condition. The simulation results are val…
Chaotic edge density fluctuations in the Alcator C-Mod tokamak
Ziyan Zhu, Anne White, Troy Carter +2
Analysis of the time series obtained with the O-Mode reflectometer (Rhodes et al 1997 Plasma Phys. and Control. Fusion 40 (1998) 493-510) and the gas puff imaging (Cziegler, I. et…
Kinetic modeling of divertor heat load fluxes in the Alcator C-Mod and DIII-D tokamaks
A. Y. Pankin, T. Rafiq, A. H. Kritz +8
The guiding-center kinetic neoclassical transport code, XGC0, [C.S. Chang et. al, Phys. Plasmas 11, 2649 (2004)] is used to compute the heat fluxes and the heat-load width in the o…
Burst statistics in Alcator C-Mod SOL turbulence
O. E. Garcia, I. Cziegler, R. Kube +2
Bursty fluctuations in the scrape-off layer (SOL) of Alcator C-Mod have been analyzed using gas puff imaging data. This reveals many of the same fluctuation properties as Langmuir…
On the statistics of edge fluctuations: comparative study between various fusion devices
F. Sattin, M. Agostini, P. Scarin +12
In this paper we present a statistical study of edge fluctuations taken with the Gas Puffing Imaging (GPI) diagnostics. We carry out a comparison of GPI signal from an extensive da…
