Role of plasmoid drift in the efficiency and reliability of shattered pellet injection

open access: yesPlasma Physics and Controlled Fusion
Abstract The role of plasmoid drifts towards the tokamak low field side and associated rocket motion of solid fragments in the material assimilation of shattered pellet injection (SPI) is investigated. In particular, a trace neon SPI scheme, where a small amount of neon is added to the pellet, envisaged to ...

Simulation of shattered pellet injections with plasmoid drifts in ASDEX Upgrade and ITER

open access: yesPlasma Physics and Controlled Fusion
Abstract Pellet injection is an important means to fuel and control discharges and mitigate disruptions in reactor-scale fusion devices. To accurately assess the efficiency of these applications, it is necessary to account for the drift of the ablated material towards the low-field side.

Non-linear MHD modelling of transients in tokamaks: a review of recent advances with the JOREK code

open access: yesNuclear Fusion
Transient magneto-hydrodynamic (MHD) events like edge localized modes (ELMs) or disruptions are a concern for magnetic confinement fusion power plants. Research with the MHD code JOREK towards understanding control of such instabilities is reviewed here ...

Overview of ASDEX upgrade results in view of ITER and DEMO

open access: yesNuclear Fusion
Experiments on ASDEX Upgrade (AUG) in 2021 and 2022 have addressed a number of critical issues for ITER and EU DEMO. A major objective of the AUG programme is to shed light on the underlying physics of confinement, stability, and plasma exhaust in order ...
