Evolution of SPI-induced disruptions in ASDEX Upgrade
P. Heinrich, G. Papp, S. Jachmich +23
Disruptions are a major concern for future fusion reactors based on the tokamak principle. To ensure machine protection, the thermal loads and vessel forces that arise during disru…
Non-linear MHD modelling of shattered pellet injection in ASDEX Upgrade
W. Tang, M. Hoelzl, M. Lehnen +11
Shattered pellet injection (SPI) is selected for the disruption mitigation system in ITER, due to deeper penetration, expected assimilation efficiency and prompt material delivery.…
Simulation of Shattered Pellet Injections with Plasmoid Drifts in ASDEX Upgrade and ITER
O. Vallhagen, L. Antonsson, P. Halldestam +7
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 applica…
Modelling of shattered pellet injection experiments on the ASDEX Upgrade tokamak
Ansh Patel, Akinobu Matsuyama, Gergely Papp +13
In a shattered pellet injection (SPI) system the penetration and assimilation of the injected material depends on the speed and size distribution of the SPI fragments. ASDEX Upgrad…
