The best validated fusion devices are tokamaks, which are vulnerable to large scale plasma instabilities called “disruptions” that can stop the reaction and damage the device.
The dynamics of point charges in a plasma The dynamics of charged objects, such as ions or electrons in a plasma, obey very similar laws when their velocities is small enough
Vlasov-Poisson System: A Kinetic Plasma Model Whatisaplasma? I‘Fourth’stateofmatter,andmostabundantformofordinarymatter. …
In this talk we review the advances made in adaptive fully Lagrangian electrostatic plasma simulations. The method is based on hiaerarical fast summation, the Boundary Integral Treecode (BIT), and …
A collisionless plasma is modeled by the Vlasov-Poisson system in three space dimensions. A fixed background of positive charge, which is independent of time and space, is assumed.
Partially magnetized plasma in Hall thrusters includes complex mechanisms: Dynamic interaction between acceleration and ionization (Breathing mode) Wall interactions (Near-wall sheath, SEE, …
We discuss a new, conservative, fully implicit 2D-‐3V particle-‐in-‐cell algorithm for non-‐radiative, electromagnetic kinetic plasma simulations, based on the Vlasov-‐Darwin model [1].
Many important qualities of nuclear plasma confinement devices can be determined via the Poincare plot of a symplectic return map. These qualities include the locations of the magnetic core (good for …
ICERM - Kinetic Theory and Computation
It is an indispensable tool in the mathematical description of applications in physical and social sciences, from its origin in dilute gases, to wide applications such as semi-conductors, polymers, cells, plasma, …
Neutrino Plasma Instabilities Because neutrinos feel potential from other neutrinos:
