Effect of toroidal Alfvén Eigenmode nonlinearity on edge localized mode in HL-2A NBI heated H-mode plasmas

Nuclear Fusion
The present paper reports the observation of shear Alfvénic wave fluctuations prior to the edge localized mode (ELM) crash in HL-2A NBI H-mode plasmas.

Formation of the Injection Function of Solar Energetic Particles in Gradual Events

The Astrophysical Journal, 2023
We present a model for solar energetic particle injection into interplanetary space in gradual events, in which particle acceleration occurs in a limited region of the solar atmosphere.

The Effect of Large-scale Magnetic Fluctuations on Energetic Particle Profiles across Interplanetary Shocks

The Astrophysical Journal
In situ observations of energetic particles associated with interplanetary (IP) shocks, known as energetic storm particle (ESP) events, often show time-intensity profiles quite different from predictions of classical diffusive shock acceleration theory ...

Energetic Particle Forcing of the Northern Hemisphere winter stratosphere: Comparison to solar irradiance forcing

Frontiers in Physics, 2014
Variation in solar irradiance is considered an important factor in natural climate forcing. Variations in the solar UV in particular are now regarded as a major source of decadal variability in the stratosphere, influencing surface climate through ...

Energetic particle investigation using the ERNE instrument [PDF]

Annales Geophysicae, 1996
During solar flares and coronal mass ejections, nuclei and electrons accelerated to high energies are injected into interplanetary space. These accelerated particles can be detected at the SOHO satellite by the ERNE instrument.

Parker Solar Probe Observations of Energetic Particles in the Flank of a Coronal Mass Ejection Close to the Sun

The Astrophysical Journal
We present an event observed by Parker Solar Probe (PSP) at ∼0.2 au on 2022 March 2 in which imaging and in situ measurements coincide. During this event, PSP passed through structures on the flank of a streamer blowout coronal mass ejection (CME ...

Energetic particle driven Alfvén eigenmodes and associated energetic particle redistribution in a tokamak burning plasma

Nuclear Fusion
Energetic-particle driven Alfvén eigenmodes (AEs) and associated redistribution of energetic particles in phase space are investigated using kinetic-magnetohydrodynamic (MHD) hybrid simulations for a tokamak burning plasma with weakly reversed magnetic ...

Magnetic topology of coronal mass ejection events out of the ecliptic: Ulysses/HI-SCALE energetic particle observations [PDF]

Annales Geophysicae, 2003
Solar energetic particle fluxes (Ee > 38 keV) observed by the ULYSSES/HI-SCALE experiment are utilized as diagnostic tracers of the large-scale structure and topology of the Interplanetary Magnetic Field (IMF) embedded within two well ...

Very Large and Long-lasting Anisotropies Caused by Sunward Streaming Energetic Ions: Solar Orbiter and STEREO A Observations

The Astrophysical Journal Letters
The anisotropy of energetic particles provides essential information to help resolve the underlying fundamental physics of their spatial distributions, injection, acceleration, and transport processes. In this work, we report an energetic ion enhancement
