Spacecraft heat shield study in the DIII-D tokamak
Dmitri M. Orlov, Evdokiya G. Kostadinova, Igor Bykov +33
We report a new experimental platform developed at the DIII-D National Fusion Facility to investigate carbon ablation and spallation under extreme heat fluxes relevant to fusion pl…
Modeling Torque Induced Alignment in a Dusty Plasma System
Benny Rodriguez Saenz, Diana Jimenez Marti, Lorin Swint Matthews +1
Irregular dust aggregates immersed in plasma sheaths experience several orientation-dependent torques that can modify their rotational dynamics and stability. Here, we investigate…
Ion wake-mediated dust interactions under PK-4 conditions: a generalized and compact potential formulation
Diana Jimenez Marti, Benny Rodriguez Saenz, Peter Hartmann +3
Dusty plasmas, composed of electrons, ions, neutral particles, and charged dust grains, exhibit self-organization phenomena such as string-like structures observed in microgravity…
DustNET: enabling machine learning and AI models of dusty plasmas
Zhehui Wang, Justin C. Burton, Niklas Dormagen +30
Dusty plasmas are ubiquitous throughout the universe, spanning laboratory and industrial plasmas, fusion devices, planetary environments, cometary comae, and interstellar media. De…
Sparse identification of effective microparticle interaction potential in dusty plasma from simulation data
Zachary Brooks Howe, Lorin Swint Matthews, Truell Hyde +2
Identification of the particle interaction potential is a challenging and important task in dusty plasma, colloids, and smart materials as it allows the characterization of structu…
Anisotropic anomalous diffusion and nonequilibrium in microgravity dusty plasma. Part Two: Spectral Analysis
Bradley R. Andrew, Luca Guazzotto, Lorin S. Matthews +2
Anisotropic anomalous dust diffusion in microgravity dusty plasma is investigated using experimental data from the Plasmakristall-4 (PK-4) facility on board the International Space…
