Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]
, 2012 We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Progress in particle-beam-driven inertial fusion research: Activities in Japan
Matter and Radiation at Extremes, 2018 Research activities in Japan relevant to particle beam inertial fusion are briefly reviewed. These activities can be ascended to the 1980s. During the past three decades, significant progress in particle beam fusion, pulsed power systems, accelerator ...

Magnetospheric convection electric field dynamics andstormtime particle energization: case study of the magneticstorm of 4 May 1998 [PDF]
Annales Geophysicae, 2004 It is shown that narrow channels of high electric field are an effective mechanism for injecting plasma into the inner magnetosphere. Analytical expressions for the electric field cannot produce these channels of intense plasma flow, and thus, result ...

Time-Domain Modeling of RF Antennas and Plasma-Surface Interactions
EPJ Web of Conferences, 2017 Recent advances in finite-difference time-domain (FDTD) modeling techniques allow plasma-surface interactions such as sheath formation and sputtering to be modeled concurrently with the physics of antenna near- and far-field behavior and ICRF power flow.

Nongyrotropic particle distributions in space plasmas [PDF]
Annales Geophysicae, 1999 In nonstationary, strong inhomogeneous or open plasmas particle orbits are rather complicated. If the nonstationary time scale is smaller than the gyration period, if the inhomogeneity scale is smaller than the gyration radius, i.e. at magnetic plasma

A quantitative model for cyclotron wave-particle interactions at the plasmapause [PDF]
Annales Geophysicae, 1998 The formation of a zone of energetic electron precipitation by the plasmapause, a region of enhanced plasma density, following energetic particle injection during a magnetic storm, is analyzed.

Physical Fidelity in Particle-In-Cell Modeling of Small Debye-Length Plasmas [PDF]
AIP Conference Proceedings, 2009 The connection between macro‐particle shape functions and non‐physical phase‐space “heating” in the particle‐in‐cell (PIC) algorithm is examined. The development of fine‐scale phase‐space structures starting from a cold initial condition is shown to be related to spatial correlations in the interpolated fields used in the Lorentz force.
