Author(s): Zhen-Ke Dou, Chong Lv, Yousef I. Salamin, Nan Zhang, Feng Wan, Zhong-Feng Xu, and Jian-Xing Li

Compact spin-polarized positron accelerators play a major role in promoting significant positron application research, which typically require high acceleration gradients and polarization degrees, both of which, however, are still greatly challenging. Here, we put forward a spin-polarized positron a…

Author(s): Qingbo Luo, Xin Liang, Chengliang Lin, Xinlian Zhang, Jianpeng Liu, Cheng Gao, Yong Hou, and Jianmin Yuan

In hot dense plasma, the interaction between charged particles leads to the ionization potential depression (IPD), which further affects the physical properties of plasma, such as opacity and equation of state. The experiment of IPD of solid-density Al plasma has indicated that present theoretical m…

Nonlinear saturation of the two-plasmon decay instability in magnetized plasmas

Tue, 03/18/2025 - 10:00

Author(s): X. X. Li, R. J. Cheng, Qing Wang, D. J. Liu, S. Y. Lv, Z. M. Huang, S. T. Zhang, Z. J. Chen, Z. Y. Xu, Qiang Wang, Z. J. Liu, L. H. Cao, C. Y. Zheng, and X. T. He

It is shown that the Landau damping of electron plasma waves (EPWs) is significantly enhanced in a transverse magnetic field with tens of teslas due to a strong modification of the electron velocity distribution function formed in the two-plasmon-decay (TPD) process. The Landau damping even in the r…

Resonance broadening effects of weak turbulence on Earth's radiation belt electrons

Tue, 03/18/2025 - 10:00

Author(s): Xiongdong Yu, Zhigang Yuan, Dedong Wang, Oliver Allanson, and Samuel Hunter

The dynamics of electrons in space plasmas, such as the earth’s radiation belts, are affected by the presence of wave turbulence, even when a resonance condition is not satisfied. The authors propose an expression to describe this resonance broadening effect, and find that it compares well with test particle simulation results. The study is applied to whistler-mode chorus waves in the radiation belt’s electrons, but can be easily extended to a wide range of systems.

Author(s): Louis Jose, James C. Welch, III, Timothy D. Tharp, and Scott D. Baalrud

Strongly magnetized plasmas, characterized by having a gyrofrequency larger than the plasma frequency (β=ωc/ωp≫1), are known to exhibit novel transport properties. Previous works studying pure electron plasmas have shown that strong magnetization significantly inhibits energy exchange between parall…

Author(s): William Trickey, T. J. B. Collins, I. V. Igumenshchev, V. N. Goncharov, and A. Shvydky

The dynamic-shell concept for inertial confinement fusion (ICF) uses an initially homogeneous target and a carefully shaped laser pulse to form a shell and implode it. The laser pulse consists of a series of pickets that drive shocks into the target. The first few shocks converge inwards and rebound…

Author(s): Yichen Fu, Justin R. Angus, Hong Qin, and Vasily I. Geyko

Coulomb collision is a fundamental diffusion process in plasmas that can be described by the Landau-Fokker-Planck (LFP) equation or the stochastic differential equation (SDE). While energy and momentum are conserved exactly in the LFP equation, they are conserved only on average by the conventional …
