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…
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…
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…
Effect of Controlled Magnetic Island Bifurcation on Electron Diffusion
Jessica Eskew, D. M. Orlov, B. Andrew +7
Magnetic islands strongly influence cross-field electron transport in magnetized plasmas. In particular, bifurcations of the island topology modify the number and location of O-poi…
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…
Structural States of Filamentary Microgravity Dusty Plasma
Emerson Gehr, Abigail Terrell, Katrina Vermillion +7
This study investigates the filamentary structural states of microgravity dusty plasma using data from the Plasmakristall-4 (PK-4) facility on board the International Space Station…
