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…
Aspherical PIC code (APIC) for modeling non-spherical dust in plasmas using shape-conforming coordinates
R. D. Smirnov, S. I. Krasheninnikov
The 2D3V Aspherical Particle-in-Cell (APIC) code is developed for modeling of interactions of non-spherical dust grains with plasmas. It simulates the motion of plasma electrons an…
On the force exerted on a non-spherical dust grain from homogeneous, stationary, non-magnetized plasma
S. I. Krasheninnikov, R. D. Smirnov
It is shown that stationary non-spherical dust grain immersed into stationary non-magnetized plasma can experience a force caused by the grain-plasma interactions.
Anomalous edge plasma transport, neutrals, and divertor plasma detachment
Yanzeng Zhang, Sergei I. Krasheninnikov, Rebecca Masline +1
An impact of neutrals on anomalous edge plasma transport and zonal flow (ZF) is considered. As an example, it is assumed that edge plasma turbulence is driven by the resistive drif…
