On the feasibility of model-based feedback control of vertical instability growth rate using out-vessel coils in ARC-like scenarios
Arunav Kumar, Cesar Clauser, Theodore Golfinopoulos +1
In this work, we propose a model-based feedback controller that regulates the vertical instability growth rate () of a high-elongation, double-null tokamak directly, using…
Steady state, core, operational optimization of an ARC-like tokamak via plasma composition and shape
A. Saltzman, P. Rodriguez-Fernandez, A. Ho +8
Impurity composition, plasma shape, and pedestal density all provide strong levers on fusion power. Here, we explore the ways in which their variation changes fusion power and seek…
Simulations of grain growth in tungsten armor materials under ARC plasma edge operation conditions using an integrated plasma-edge/materials model
Jinxin Yu, Nithin Mathew, Sophie Blondel +5
An integrated model of grain growth deuterium-exposed tungsten polycrystals, consisting of a two-dimensional vertex dynamics model fitted to atomistic data, has been developed to a…
Conceptual study on using Doppler backscattering to measure magnetic pitch angle in tokamak plasmas
AK Yeoh, VH Hall-Chen, QT Pratt +8
We introduce a new approach to measure the magnetic pitch angle profile in tokamak plasmas with Doppler backscattering (DBS), a technique traditionally used for measuring flows and…
Interpreting Radial Correlation Doppler Reflectometry using Gyrokinetic Simulations
J. Ruiz Ruiz, F. I. Parra, V. H. Hall-Chen +12
A linear response, local model for the DBS amplitude applied to gyrokinetic simulations shows that radial correlation Doppler reflectometry measurements (RCDR, Schirmer et al., Pla…
