Solar Energetic Particles

Space Science Reviews, 2000
The emission of energetic particles from the Sun is one of the major manifestations of high energy astrophysics and is related to a variety of astrophysical and geophysical phenomena in the heliosphere. An event of solar energetic particles (SEP) is seen as a sudden rise of the counting rate of the background galactic cosmic rays reaching a high value ...

COSMIC RAY SOURCE AND SOLAR ENERGETIC PARTICLES

Problems of Atomic Science and Technology, 2023
The acceleration of particles to the high energy is one of the key issues of solar physics, cis-lunar irradiations, astrophysics, and astroparticle physics. With the development of space astronomy, people started to realize that plasma disturbances in solar flares, Earth’s magnetosphere, and interplanetary space can also produce a large population of ...

SOLAR ENERGETIC PARTICLES

International Journal of Modern Physics A, 2005
Energetic particles recorded in the Earth environment and in interplanetary space have a multitude of origins, i.e. acceleration and propagation histories. At early days practically all sufficiently energetic particles were considered to have come either from solar flares or from interstellar space.

Solar Energetic Particle Isotopic Composition

Space Science Reviews, 1998
We discuss isotopic abundance measurements of heavy (6 ≤ Z ≤ 14) solar energetic particles with energies from ∼15 to 70 MeV/nucleon, focusing on new measurements made on SAMPEX during two large solar particle events in late 1992. These measurements are corrected for charge/mass dependent acceleration effects to obtain estimates of coronal isotopic ...
