An upper pressure limit for low-Z benign termination of runaway electron beams in TCV
M Hoppe, J Decker, U Sheikh +17
We present a model for the particle balance in the post-disruption runaway electron plateau phase of a tokamak discharge. The model is constructed with the help of, and applied to,…
Anomalous Spectroscopical Effects in an Antiferromagnetic Semiconductor
Michal Hubert, Tomáš Maleček, Kyo-Hoon Ahn +6
Following the recent observation of anomalous Hall effect in antiferromagnetic hexagonal MnTe thin films, related phenomena at finite frequencies have come into focus. Magnetic cir…
Laser initiated p-11B fusion reactions in petawatt high-repetition-rates laser facilities
M. Scisciò, G. Petringa, Z. Zhu +43
Driving the nuclear fusion reaction p+11B -> 3 alpha + 8.7 MeV in laboratory conditions, by interaction between high-power laser pulses and matter, has become a popular field of re…
Phase Composition of AlTiNbMoV, AlTiNbTaZr and AlTiNbMoCr Refractory Complex Concentrated Alloys: A Correlation of Predictions and Experiment
Jiří Kozlík, František Lukáč, Mariano Casas Luna +5
Designing complex concentrated alloys (CCA), also known as high entropy alloys (HEA), requires reliable and accessible thermodynamic predictions due to vast space of possible compo…
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…
Exploring the operational limits of poloidal and helical arrays of Mirnov coils in stellarators by means of a synthetic diagnostic
P. Pons-Villalonga, A. Cappa, J. Martínez-Fernández +3
A synthetic Mirnov coils diagnostic for non-axisymmetric magnetic configurations is presented and used to study the capabilities of the poloidal array of single-axis coils and the…
Enabling High-Throughput Parallel I/O in Particle-in-Cell Monte Carlo Simulations with openPMD and Darshan I/O Monitoring
Jeremy J. Williams, Daniel Medeiros, Stefan Costea +14
Large-scale HPC simulations of plasma dynamics in fusion devices require efficient parallel I/O to avoid slowing down the simulation and to enable the post-processing of critical i…
Scanning acoustic microscopy characterization of cold sprayed coatings deposited on grooved substrates
Martin Koller, Jan Cizek, Michaela Janovská +4
The effect of non-planar substrate surface on homogeneity and quality of cold sprayed (CS) deposits was studied by scanning acoustic microscopy (SAM). Fe coatings were cold sprayed…
Understanding the Impact of openPMD on BIT1, a Particle-in-Cell Monte Carlo Code, through Instrumentation, Monitoring, and In-Situ Analysis
Jeremy J. Williams, Stefan Costea, Allen D. Malony +7
Particle-in-Cell Monte Carlo simulations on large-scale systems play a fundamental role in understanding the complexities of plasma dynamics in fusion devices. Efficient handling a…
Damage mechanisms in polyalkenes irradiated with ultra-short XUV/x-ray laser pulses
N. Nikishev, N. Medvedev
Although polymers are widely used in laser-irradiation research, their microscopic response to high-intensity ultrafast XUV or X-ray irradiation is still largely unknown. Here we c…
High-temperature threshold of damage of SiC by swift heavy ions
D. I. Zainutdinov, V. A. Borodin, S. A. Gorbunov +5
At ambient conditions, SiC is known to be resistant to irradiation with swift heavy ions (SHI) decelerating in the electronic stopping regime. However, there is no experimental dat…
Multi-temperature atomic ensemble: nonequilibrium evolution after ultrafast electronic excitation
Nikita Medvedev, Alexander E. Volkov
Ultrafast laser radiation or beams of fast charged particles primarily excite the electronic system of a solid driving the target transiently out of thermal equilibrium. Apart from…
