Characterizing the temporal evolution of Biermann-battery-driven magnetic reconnection in laser-ablated plasmas
T. Morita, Y. Muramoto, S. Isayama +30
This paper presents an experimental investigation of magnetic reconnection between two laser-produced expanding plasmas, focusing on the quantitative evaluation of the reconnection…
Fully nonlinear phenomenology of the bump-on-tail (BOT) instability with drag, diffusion and Krook relaxation
Shi-Jie Zhang, Lei Chang, Zhao-Ju Bo +8
Energetic-particle-driven modes in magnetically confined fusion plasmas often exhibit nonlinear frequency sweeping, reflecting complex wave-particle interactions near marginal stab…
Revealing the transient ionization dynamics and mode-coupling mechanisms of helicon discharge through a self-consistent multiphysics model
Jing-Jing Ma, Lei Chang, Ming-Yang Wu +6
Helicon plasma sources play a central role in applications ranging from material treatment to space propulsion and fusion, yet the physical processes governing their ignition, tran…
Relativistic multistage resonant and trailing-field acceleration induced by large-amplitude Alfvén waves in a strong magnetic field
S. Isayama, S. Matsukiyo, T. Sano +1
We propose a particle acceleration mechanism driven by large-amplitude Alfvén waves in a strong magnetic field. The acceleration process proceeds through multiple stages triggered…
Transition of blue-core helicon discharge
L. Chang, S. J. Zhang, J. T. Wu +10
This study explores the transitional characteristics of blue-core helicon discharge, which to our knowledge was not particularly focused on before. Parameters are measured on recen…
Electron density structure measurements with scattered intense laser beam
K. Sakai, K. Himeno, S. J. Tanaka +23
Short-pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting…
Relativistic two-wave resonant acceleration of electrons at large-amplitude standing whistler waves during laser-plasma interaction
Takayoshi Sano, Shogo Isayama, Kenta Takahashi +1
The interaction between a thin foil target and a circularly polarized laser light injected along an external magnetic field is investigated numerically by particle-in-cell simulati…
Mechanism of generating collisionless shock in magnetized gas plasma driven by laser-ablated target plasma
S. Matsukiyo, K. Oshida, S. Isayama +7
Mechanism of generating collisionless shock in magnetized gas plasma driven by laser-ablated target plasma is investigated by using one-dimensional full particle-in-cell simulation…
Collective Thomson scattering in non-equilibrium laser produced two-stream plasmas
K. Sakai, S. Isayama, N. Bolouki +12
We investigate collective Thomson scattering (CTS) in two-stream non-equilibrium plasmas analytically, numerically and experimentally. In laboratory astrophysics, CTS is a unique t…
Ion-acoustic feature of collective Thomson scattering in non-equilibrium two-stream plasmas
K. Sakai, T. Nishimoto, S. Isayama +2
We theoretically and numerically investigate the ion-acoustic features of collective Thomson scattering (CTS) in two-stream plasmas. When the electron distribution functions of two…
Detection of current-sheet and bipolar ion flows in a self-generated antiparallel magnetic field of laser-produced plasmas for magnetic reconnection research
T. Morita, S. Matsukiyo, S. Isayama +18
Magnetic reconnection in laser-produced magnetized plasma is investigated by using optical diagnostics. The magnetic field is generated via Biermann battery effect, and the inverse…
High-power laser experiment on developing supercritical shock propagating in homogeneously magnetized plasma of ambient gas origin
S. Matsukiyo, R. Yamazaki, T. Morita +30
A developing supercritical collisionless shock propagating in a homogeneously magnetized plasma of ambient gas origin having higher uniformity than the previous experiments is form…
Particle acceleration by counter-propagating circularly polarized Alfvén waves
S. Isayama, K. Takahashi, S. Matsukiyo +1
Counterpropagating Alfvén waves are ubiquitously observed in many astrophysical environments, such as a star surface and a planetary foreshock. We discuss an efficient particle acc…
