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…

Optimisation of Gyrokinetic Microstability Using Adjoint Methods
Georgia Acton, Michael Barnes, Sarah Newton +1
Microinstabilities drive turbulent fluctuations in inhomogeneous, magnetized plasmas. In the context of magnetic confinement fusion devices, this leads to an enhanced transport of…

Runaway Electron Dynamics in ITER Disruptions with Shattered Pellet Injections
Oskar Vallhagen, Lise Hanebring, Javier Artola +6
This study systematically explores the parameter space of disruption mitigation through shattered pellet injection in ITER with a focus on runaway electron dynamics, using the disr…
