Electronic heat conductivity in a two-temperature state
Nikita Medvedev, Fedor Akhmetov, Igor Milov
Laser irradiation of materials is most commonly modeled with the two-temperature model (TTM), or its combination with molecular dynamics, TTM-MD. For such modeling, the electronic…
Divertor shaping with neutral baffling as a solution to the tokamak power exhaust challenge
K. Verhaegh, J. R. Harrison, D. Moulton +20
Exhausting power from the hot fusion core to the plasma-facing components is one of the biggest challenges in fusion energy. The MAST Upgrade tokamak uniquely integrates strong con…
Magnetic flutter effect on validated edge turbulence simulations
Kaiyu Zhang, Wladimir Zholobenko, Andreas Stegmeir +2
Small magnetic fluctuations () are intrinsically present in a magnetic confinement plasma due to turbulent currents. While the perpendicular transport of part…
Electron-phonon coupling in semiconductors at high electronic temperatures
Nikita Medvedev
A nonperturbative dynamical coupling approach based on tight-binding molecular dynamics is used to evaluate the electron-ion (electron-phonon) coupling parameter in irradiated semi…
Atomic-Scale Insights into Damage Produced by Swift Heavy Ions in Polyethylene
P. Babaev, F. Akhmetov, S. Gorbunov +4
We describe the formation of swift heavy ion tracks in polyethylene (PE) by combining the Monte Carlo code TREKIS, which models electronic excitation in nanometric proximity of the…
Leveraging HPC Profiling & Tracing Tools to Understand the Performance of Particle-in-Cell Monte Carlo Simulations
Jeremy J. Williams, David Tskhakaya, Stefan Costea +3
Large-scale plasma simulations are critical for designing and developing next-generation fusion energy devices and modeling industrial plasmas. BIT1 is a massively parallel Particl…
Direct laser acceleration in underdense plasmas with multi-PW lasers: a path to high-charge, GeV-class electron bunches
R. Babjak, L. Willingale, A. Arefiev +1
The direct laser acceleration (DLA) of electrons in underdense plasmas can provide 100s of nC of electrons accelerated to near-GeV energies using currently available lasers. Here w…
Materials under XUV irradiation: effects of structure, size, and temperature
Nikita Medvedev
This proceeding discusses the impact of XUV/X-ray irradiation on materials, and how their response is affected by temperature, size, and structure. When materials are exposed to in…
Revealing Non-equilibrium and Relaxation in Warm Dense Matter
Jan Vorberger, Thomas R. Preston, Nikita Medvedev +4
Experiments creating extreme states of matter almost invariably create non-equilibrium states. These are very interesting in their own right but need to be understood even if the u…
Probing non-linear MHD stability of the EDA H-mode in ASDEX Upgrade
A Cathey, M Hoelzl, L Gil +11
Regimes of operation in tokamaks that are devoid of large ELMs have to be better understood to extrapolate their applicability to reactor-relevant devices. This paper describes non…
High-precision FoM measurement setup for Ti:Sapphire crystals
Vojtech Miller, Karel Zidek
The figure of merit (FoM) of Ti:Sapphire (Ti:Sa) crystals is a generally used means to evaluate the quality of the crystals. Despite the importance of Ti:Sa, the question of FoM me…
Equations of motion governing the dynamics of the exceptional points of parameterically dependent nonhermitian Hamiltonians
Milan Šindelka, Pavel Stránský, Pavel Cejnar
We study exceptional points (EPs) of a nonhermitian Hamiltonian whose parameters and . As the real control parameter is vari…
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…
