The Energetic Particle Detector [PDF]

Astronomy & Astrophysics, 2020
After decades of observations of solar energetic particles from space-based observatories, relevant questions on particle injection, transport, and acceleration remain open. To address these scientific topics, accurate measurements of the particle properties in the inner heliosphere are needed. In this paper we describe the Energetic Particle Detector (

Solar energetic particle variations [PDF]

Advances in Space Research, 2004
The population of energetic particles in the heliosphere changes from solar maximum to solar minimum. The ultimate driver for those variations is the Sun. Solar variability is reflected in the dynamics of the large-scale structure of the heliosphere, the solar output of energetic particles and most definitively in the intensity, energy and composition ...

Acceleration and Propagation of Solar Energetic Particles [PDF]

Space Science Reviews, 2017
Solar Energetic Particles (SEPs) are an important component of Space Weather, including radiation hazard to humans and electronic equipment, and the ionisation of the Earth's atmosphere. We review the key observations of SEPs, our current understanding of their acceleration and transport, and discuss how this knowledge is incorporated within Space ...

Solar Energetic Particle “Ground-Level Enhancements” and the Solar Cycle [PDF]

Solar Physics, 2022
Abstract Severe geomagnetic storms appear to be ordered by the solar cycle in a number of ways: They occur more frequently close to solar maximum and declining phase, are more common in larger solar cycles and show different patterns of occurrence in odd-and even-numbered solar cycles.

Solar flares and energetic particles [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Solar flares are now observed at all wavelengths from γ -rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released

Current status and possible extension of the global neutron monitor network

Journal of Space Weather and Space Climate, 2020
The global neutron monitor network has been successfully used over several decades to study cosmic ray variations and fluxes of energetic solar particles. Nowadays, it is used also for space weather purposes, e.g. alerts and assessment of the exposure to

Ulysses COSPIN observations of cosmic rays and solar energetic particles from the South Pole to the North Pole of the Sun during solar maximum [PDF]

Annales Geophysicae, 2003
In 2000–2001 Ulysses passed from the south to the north polar regions of the Sun in the inner heliosphere, providing a snapshot of the latitudinal structure of cosmic ray modulation and solar energetic particle populations during a period near ...

Transport of Solar Energetic Particles [PDF]

International Astronomical Union Colloquium, 1994
AbstractNew developments in the understanding of the interplanetary transport of solar cosmic rays are reviewed. Based on carefully analyzed solar particle events observed on the Helios and ISEE 3 spacecraft, the relation of transport parameters to the structure of the interplanetary magnetic field is discussed.

Energy Spectrum of Solar Energetic Electron Events over 25 Years

The Astrophysical Journal, 2023
We investigate the peak flux energy spectrum of 458 solar energetic electron (SEE) events with a clear velocity dispersion detected at energies from ≤4.2 to ≥108 keV by Wind/3DP from 1994 December through 2019 December, utilizing a pan-spectrum fitting ...

Review of Solar Energetic Particle Models [PDF]

, 2022
Solar Energetic Particles (SEP) events are interesting from a scientific perspective as they are the product of a broad set of physical processes from the corona out through the extent of the heliosphere, and provide insight into processes of particle acceleration and transport that are widely applicable in astrophysics. From the operations perspective,
