First divertor exposure experiments of a renewable boron pebble aggregate in DIII-D
Erick Martinez-Loran, Angelica Ottaviano, Santhosh T. A. Kumar +21
Boron pebble aggregate was tested for the first time as a high-heat-flux granular plasma-facing material in a tokamak divertor. Exposures of up to $q_{\parallel} = \SI{80}{\MW\per\…
Plasma Confinement State Classification in Fusion Power Plants: Profile Reflectometer and Ensemble Diagnostics
Randall Clark, Vacslav Glukhov, Georgy Subbotin +4
As Fusion Pilot Plants (FPPs) are increasingly viewed as within reach, many engineering challenges remain. Not many diagnostics are expected to be available in a reactor environmen…
Predicting core transport in ITER baseline discharges with neon injections
Dmitri M Orlov, Joseph McClenaghan, Jeff Candy +4
Achieving self-consistent performance predictions for ITER requires integrated modeling of core transport and divertor power exhaust under realistic impurity conditions. We present…
Reconstruction-free magnetic control of DIII-D plasma with deep reinforcement learning
G. F. Subbotin, D. I. Sorokin, M. R. Nurgaliev +9
Precise control of plasma shape and position is essential for stable tokamak operation and achieving commercial fusion energy. Traditional control methods rely on equilibrium recon…
