Runaway electron-induced plasma facing component damage in tokamaks
S. Ratynskaia, M. Hoelzl, E. Nardon +31
This Roadmap article addresses the critical and multifaceted challenge of plasma-facing component (PFC) damage caused by runaway electrons (REs) in tokamaks, a phenomenon that pose…
On the minimum transport required to passively suppress runaway electrons in SPARC disruptions
R. A. Tinguely, I. Pusztai, V. A. Izzo +8
In [V.A. Izzo et al 2022 Nucl. Fusion 62 096029], state-of-the-art modeling of thermal and current quench (CQ) MHD coupled with a self-consistent evolution of runaway electron (RE)…
Runaway electron deconfinement in SPARC and DIII-D by a passive 3D coil
V. A. Izzo, I. Pusztai, K. Särkimäki +7
The operation of a 3D coil--passively driven by the current quench loop voltage--for the deconfinement of runaway electrons is modeled for disruption scenarios in the SPARC and DII…
Scenario adaptive disruption prediction study for next generation burning-plasma tokamaks
J. Zhu, C. Rea, R. S. Granetz +10
Next generation high performance (HP) tokamaks risk damage from unmitigated disruptions at high current and power. Achieving reliable disruption prediction for a device's HP operat…
Hybrid deep learning architecture for general disruption prediction across tokamaks
J. X. Zhu, C. Rea, K. Montes +3
In this paper, we present a new deep learning disruption prediction algorithm based on important findings from explorative data analysis which effectively allows knowledge transfer…
Experimental and synthetic measurements of polarized synchrotron emission from runaway electrons in Alcator C-Mod
R. A. Tinguely, M. Hoppe, R. S. Granetz +2
This paper presents the first experimental analysis of polarized synchrotron emission from relativistic runaway electrons (REs) in a tokamak plasma. Importantly, we show that the p…
High-resolution disruption halo current measurements using Langmuir probes in Alcator C-Mod
RA Tinguely, RS Granetz, A Berg +3
Halo currents generated during disruptions on Alcator C-Mod have been measured with Langmuir "rail" probes. These rail probes are embedded in a lower outboard divertor module in a…
Measurements of runaway electron synchrotron spectra at high magnetic fields in Alcator C-Mod
R. A. Tinguely, R. S. Granetz, M. Hoppe +1
In the Alcator C-Mod tokamak, runaway electron (RE) experiments have been performed during low density, flattop plasma discharges at three magnetic fields: 2.7, 5.4, and 7.8 T, the…
SOFT: A synthetic synchrotron diagnostic for runaway electrons
Mathias Hoppe, Ola Embréus, R. Alexander Tinguely +3
Improved understanding of the dynamics of runaway electrons can be obtained by measurement and interpretation of their synchrotron radiation emission. Models for synchrotron radiat…
