Summary: A particle simulation code has been developed for the simulation of electron cyclotron resonance ion source (ECRIS), taking into account the interaction between plasma and potential field, as well as various particle collisions. The stable distributions of high-energy electrons are obtained and used in the subsequent simulation of ECRIS operation. The results of the plasma potential and charge density are analyzed from the perspective of plasma diffusion.

Summary: Burning plasma state has been achieved at the US National Ignition Facility using indirect-drive inertial-confinement fusion. More efficient hohlraums and improved symmetry control have allowed for effective heating by alpha particles from fuel fusion reactions. This is significant for the progress of inertial-confinement fusion.

Summary: In this study, we systematically theoretically investigate strong field tunneling ionization of noble-gas atoms from He to Kr using elliptically polarized laser pulses in the attoclock setup. Our results suggest that the attoclock offset angle is entirely attributed to the Coulomb field of the ion remainder.

Summary: This study proposes a method to achieve coherent Cherenkov radiation using superluminal plasma wake. Through simulations and theoretical modeling, it is shown that this radiation has ultra-short duration, high intensity, and excellent directionality. Furthermore, the central frequency of the radiation can be easily tuned over a wide range.

Summary: Simulations of energetic plumes from plasma thrusters play a crucial role in estimating their performances and interactions with spacecraft. This study focuses on the numerical discretization of the electron fluid model in a 3D hybrid simulator, comparing finite-differences (FD) and finite-volumes (FV) approaches. The results show that the FV scheme outperforms the FD scheme, especially for magnetized plumes with high Hall parameters.

Summary: This study shows that magnetically dominated turbulence in pair plasmas subject to strong synchrotron cooling can generate a nonthermal particle spectrum with a hard power-law range, and the particle spectrum becomes even harder over time. These findings have important implications for understanding nonthermal emission from high-energy astrophysical sources.

Summary: The aim of the PANDORA project is to measure the decay rates of beta radionuclides in plasma as a function of the ionization stage. This paper presents the results of applying simulation tools to the PANDORA plasma for the first time, including electromagnetic calculations and electron dynamics. The distribution of different electron populations, especially the warm component that affects the distribution of ion charge states, will be shown. The close relation between the results and the evaluation of in-plasma nuclear decays will also be explained.

Summary: This study establishes a three-dimensional model using the level-set method to simulate the migration of a sessile droplet on a substrate with a temperature gradient. The effects of various factors on droplet migration are investigated, and it is found that the migration direction and speed vary with different contact angles and other parameters. The findings provide guidance for controlling the migration of sessile droplets.

Summary: This study investigates the ignition of an atmospheric pressure methane/air mixture using Nanosecond Repetitively Pulsed (NRP) discharges in a pin-pin configuration. Fully coupled plasma-combustion numerical simulations are performed using the AVIP and AVBP codes. The results show that the induced shock wave by strong discharges is crucial for ignition and can lead to quenching of the ignition kernels. Increasing the frequency of discharges reduces this effect and leads to faster and more stable ignition.

Summary: Experiments on a minimum-B electron cyclotron resonance ion source revealed the presence of a hump in the energy distribution of escaped electrons at 150-300 keV, which is independent of microwave power but increases with magnetic field strength. The hump formation is likely related to radio-frequency-induced momentum space diffusion, confirmed when microwave power is applied.

Summary: The three-dimensional NAM-ECRIS model is used to study metal ion production in the DECRIS-PM Electron Cyclotron Resonance Ion Source. Optimizing parameters of metal vapor injection increases extracted ion currents, particularly for highly charged calcium ions, by forming an internal barrier within the plasma. The benefits of injecting singly-charged calcium ions instead of atoms are also discussed.
