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

Conditional wave theory of environmental interactions with a quantum particle
We present an alternative formulation of quantum decoherence theory using conditional wave theory (CWT), which was originally developed in molecular physics (also known as exact factorization methods). We formulate a CWT of a classic model of collisional

Two types of ELF hiss observed at Varanasi, India [PDF]
The morphology of ELF hiss events observed at low-latitude ground station Varanasi (L = 1.07, geomagnetic latitude 14°55'N) are reported, which consist of two types: (1) events which propagated in ducted mode along the geomagnetic field line ...

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts
Efforts to model and predict energetic electron fluxes in the radiation belts are highly sensitive to local wave-particle interactions. In this study, we use multi-point measurements of precipitating and trapped electron fluxes to investigate the dynamic

Article: Heating of beam ions by ion acoustic waves [PDF]
Satellite measurements show that ion beams above the auroral acceleration region are heated to hundreds of eV in a direction perpendicular to the magnetic field. We show that ion acoustic waves may be responsible for much of this heating.

Temporal variability of quasi-linear pitch-angle diffusion
Kinetic wave-particle interactions in Earth’s outer radiation belt energize and scatter high-energy electrons, playing an important role in the dynamic variation of the extent and intensity of the outer belt.

Direct observation of a “devil’s staircase” in wave-particle interaction [PDF]
We report the experimental observation of a “devil’s staircase” in a time-dependent system considered as a paradigm for the transition to large-scale chaos in the universality class of Hamiltonian systems. A test electron beam is used to observe its non-self-consistent interaction with externally excited wave(s) in a traveling wave tube (TWT).

A new instrument for the study of wave-particle interactions in space: One-chip Wave-Particle Interaction Analyzer [PDF]
Abstract Wave-particle interactions in a collisionless plasma have been analyzed in several past space science missions but direct and quantitative measurement of the interactions has not been conducted. We here introduce the Wave-Particle Interaction Analyzer (WPIA) to observe wave-particle interactions directly by calculating the inner ...

Landau Damping of Langmuir Waves: An Alternative Derivation
In this paper, a discussion of the Landau damping of Langmuir waves is presented together with a simple derivation which does not require the application of methods of complex analysis.
