Reduced kinetic modelling of shattered pellet injection in ASDEX Upgrade
Peter Halldestam, Paul Heinrich, Gergely Papp +8
Plasma-terminating disruptions represent a critical outstanding issue for reactor-relevant tokamaks. ITER will use shattered pellet injection (SPI) as its disruption mitigation sys…
The pellet rocket effect in magnetic confinement fusion plasmas
Nico J. Guth, Oskar Vallhagen, Per Helander +3
Pellets of frozen material travelling into a magnetically confined fusion plasma are accelerated by the so-called pellet rocket effect. The non-uniform plasma heats the pellet abla…
The effect of plasmoid drifts on the pellet rocket effect in magnetic confinement fusion plasmas
N. J. Guth, O. Vallhagen, P. Helander +4
We detail here a semi-analytical model for the pellet rocket effect, which describes the acceleration of pellets in a fusion plasma due to asymmetries in the heat flux reaching the…
Data-driven discovery of a heat flux closure for electrostatic plasma phenomena
Emil R. Ingelsten, Madox C. McGrae-Menge, E. Paulo Alves +1
Progress in understanding multi-scale collisionless plasma phenomena requires employing tools which balance computational efficiency and physics fidelity. Collisionless fluid model…
Evolution of the autoresonant plasma wave excitation in two-dimensional particle-in-cell simulations
Mufei. Luo, Caterina. Riconda, Anna. Grassi +4
The generation of an autoresonantly phase-locked high amplitude plasma waves to the chirped beat frequency of two driving lasers is studied in two dimensions using particle-in-cell…
Control of autoresonant plasma beat-wave wakefield excitation
M. Luo, C. Riconda, I. Pusztai +3
Autoresonant phase-locking of the plasma wakefield to the beat frequency of two driving lasers offers advantages over conventional wakefield acceleration methods, since it requires…
