AXUV synthetic diagnostic for ASDEX Upgrade and its application for SPI simulations
Ferenc Lengyel, Weikang Tang, Matthias Hölzl +14
We introduce an Absolute eXtended UltraViolet (AXUV) diode-based camera forward-modelling tool to support the validation of mitigated disruption simulations and the interpretation…
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…
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…
Radiated energy fraction of SPI-induced disruptions at ASDEX Upgrade
Paul Heinrich, Gergely Papp, Stefan Jachmich +15
Future large tokamaks will operate at high plasma currents and high stored plasma energies. To ensure machine protection in case of a sudden loss of plasma confinement (major disru…
Tomographic reconstruction of the runaway distribution function in TCV using multispectral synchrotron images
T. A. Wijkamp, A. Perek, J. Decker +8
Synchrotron radiation observed in a quiescent TCV runaway discharge is studied using filtered camera images targeting three distinct wavelength intervals. Through the tomographic S…
Experimental investigation of the radial structure of energetic particle driven modes
L. Horvath, G. Papp, Ph. Lauber +8
Alfvén eigenmodes (AEs) and energetic particle modes (EPMs) are often excited by energetic particles (EPs) in tokamak plasmas. One of the main open questions concerning EP driven i…
