Adiabatic Wave-Particle Interaction Revisited

Plasma and Fusion Research, 2009
In this paper we calculate and visualize the dynamics of an ensemble of electrons trapping in an electrostatic wave of slowly increasing amplitude, illustrating that, despite disordering of particles in angle during the trapping transition as they pass close to X-points, there is still an adiabatic invariant for the great majority of particles that ...

Analysis of dynamic levitation process of the particle chain in a nonlinear standing wave field

Scientific Reports
This research delves into the dynamic behavior of acoustic levitation of the particle chain in a nonlinear standing wave field. Experimental acoustic levitation control tests reveal bifurcation and jump phenomena during dynamic adjustments to resonant ...

Synchronization of multiscale waveform focusing for rogue wave generation in dust acoustic wave turbulence

Physical Review Research, 2020
Rogue wave events (RWEs), uncertainly emerging localized extreme-amplitude events, ubiquitously occur in various nonlinear wave media. They have been mainly studied in the weakly disordered wave state with a single dominant wavelength scale. In this work,

Proton aurora and relativistic electron microbursts scattered by electromagnetic ion cyclotron waves

Frontiers in Astronomy and Space Sciences, 2022
Charged particle precipitation from Earth’s magnetosphere results in stunning displays of the aurora and energy transfer into the atmosphere. Some of this precipitation is caused by wave-particle interactions.

Wave-particle interactions in copper diamond

Physical Review Accelerators and Beams, 2023
In the context of wave propagation in solids caused by particle-matter interactions, the composite structure of copper diamond is believed to have a significant impact on the material’s response. This limits the accuracy of isotropic homogeneous elastic and elastic-plastic models used in earlier studies modeling the material’s behavior under such ...

Drift-compression waves propagating in the direction of energetic electron drift in the magnetosphere

Solar-Terrestrial Physics, 2017
As shown within the gyrokinetic framework, drift-compressional waves can propagate in the magnetosphere in the direction of energetic electron drift. The plasma is assumed to be composed of cold particles with an admixture of hot protons with a Maxwell ...

ULF waves with drift resonance and drift-bounce resonance energy sources as observed in artificially-induced HF radar backscatter [PDF]

Annales Geophysicae, 2001
HF radar backscatter which has been artificially-induced by a high power RF facility such as the EISCAT heater at Tromsø has been demonstrated to provide ionospheric electric field data of unprecedented temporal resolution and accuracy. Here such data

Nonlinear wave-particle interaction upstream from the Earth's bow shock [PDF]

Nonlinear Processes in Geophysics, 2000
Well-defined ring-like backstreaming ion distributions have been recently reported from observations made by the 3DP/PESA-High analyzer onboard the WIND spacecraft in the Earth's foreshock at large distances from the bow shock, which suggests a local ...

Planning for Observations of the Plasma Waves by Sounding Rockets in Antarctica

Antarctic Record, 1975
The plasma wave observations in the polar ionosphere consist of two categories; the first is for the emission due to the particle precipitation and the second is for the emissions that are thought to be generated in the magnetosphere as a result of the ...

Data processing in Software-type Wave–Particle Interaction Analyzer onboard the Arase satellite

Earth, Planets and Space, 2018
The software-type wave–particle interaction analyzer (S-WPIA) is an instrument package onboard the Arase satellite, which studies the magnetosphere. The S-WPIA represents a new method for directly observing wave–particle interactions onboard a spacecraft
