Mechanism Behind the Recombination Requirement for Benign Termination of Relativistic Electron Beams
George Su, Carl Friedrich Benedikt Zimmermann, Carlos Paz-Soldan +2
We present a first-principles explanation of the recombination requirement for benign termination of relativistic electron (RE) beams in tokamaks. Kinetic modeling including neutra…
Runaway electron avalanche and macroscopic beam formation: simulations of the DTT full power scenario
E. Emanuelli, F. Vannini, M. Hoelzl +7
The transition of the Divertor Tokamak Test (DTT) facility from its initial commissioning phase (Day-0, plasma current MA) to the full power scenario ( MA) int…
Plasmoid drift and first wall heat deposition during ITER H-mode dual-SPIs in JOREK simulations
D. Hu, F. J. Artola, E. Nardon +6
The heat flux mitigation during the Thermal Quench (TQ) by the Shattered Pellet Injection (SPI) is one of the major elements of disruption mitigation strategy for ITER. It's effici…
Nonlinear MHD modeling of soft limits in W7-AS
Rohan Ramasamy, Ksenia Aleynikova, Nikita Nikulsin +5
An important question for the outlook of stellarator reactors is their robustness against pressure driven modes, and the underlying mechanism behind experimentally observed soft $β…
Gyrokinetic simulations of neoclassical electron transport and bootstrap current generation in tokamak plasmas in the TRIMEG code
Lana Rekhviashvili, Zhixin Lu, Matthias Hoelzl +2
For magnetic confinement fusion in tokamak plasmas, some of the limitations to the particle and energy confinement times are caused by turbulence and collisions between particles i…
MHD simulations of formation, sustainment and loss of Quiescent H-mode in the all-tungsten ASDEX Upgrade
Lorenz Meier, Matthias Hoelzl, Andres Cathey +10
Periodic edge localized modes (ELMs) are the non-linear consequences of pressure-gradient-driven ballooning modes and current-driven peeling modes becoming unstable in the pedestal…
Confinement of passing and trapped runaway electrons in the simulation of an ITER current quench
Konsta Särkimäki, Javier Artola, Matthias Hoelzl
Runaway electrons (REs) present a high-priority issue for ITER but little is known about the extent to which RE generation is affected by the stochastic field intrinsic to disrupti…
A quasi-continuous exhaust scenario for a fusion reactor: the renaissance of small edge localized modes
G. F. Harrer, M. Faitsch, L. Radovanovic +13
Tokamak operational regimes with small edge localized modes (ELMs) could be a solution to the problem of large transient heat loads in future fusion reactors because they provide q…
Transition from no-ELM response to pellet ELM triggering during pedestal build-up -- insights from extended MHD simulations
S Futatani, A Cathey, M Hoelzl +6
Pellet ELM triggering is a well established scheme for decreasing the time between two successive ELM crashes below its natural value. Reliable ELM pacing has been demonstrated exp…
