A Perspective on Solar Energetic Particles

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The author has been fortunate to observe and participate in the rise of the field of solar energetic particles (SEPs), from the early abundance studies, to the contemporary paradigm of shock acceleration in large SEP events, and element abundance ...

Introduction to the interaction between energetic particles and Alfven eigenmodes in toroidal plasmas

open access: yesReviews of Modern Plasma Physics, 2018
This article is a tutorial review of the interaction between energetic particles and Alfvén eigenmodes (AEs) which is one of the important research issues for fusion burning plasmas.

Yield Function of the DOSimetry TELescope Count and Dose Rates Aboard the International Space Station

open access: yesSpace Weather, 2021
The Earth is constantly hit by energetic particles originating from galactic sources. The flux of these particles is altered by the magnetized solar wind in the heliosphere and the Earth's magnetic field.

The influence of nano-scale aluminum on the energetic potential of energetic materials: Theoretical and experimental observations [PDF]

open access: yesScientific Technical Review
Metal powders have been utilized for a long time in energetic materials to improve some specific performance. In recent years, metal particles in energetic materials have been reduced in size since smaller particles, particularly nano-sized, have highly ...

Spatial structure of the plasma sheet boundary layer at distances greater than 180 RE as derived from energetic particle measurements on GEOTAIL [PDF]

open access: yesAnnales Geophysicae, 1997
We have analyzed the onsets of energetic particle bursts detected by the ICS and STICS sensors of the EPIC instrument on board the GEOTAIL spacecraft in the deep magnetotail (i.e., at distances greater than 180 RE).

Identification of heavy, energetic, hadronically decaying particles using machine-learning techniques

open access: yes, 2020
Machine-learning (ML) techniques are explored to identify and classify hadronic decays of highly Lorentz-boosted W/Z/Higgs bosons and top quarks. Techniques without ML have also been evaluated and are included for comparison.

The Mediation of Collisionless Oblique Magnetized Shocks by Energetic Particles

open access: yesAstrophysical Journal, 2018
Numerous spacecraft observations reveal that many heliospheric shocks are significantly affected by the presence of energetic particles such as solar energetic particles, pickup ions (PUIs), and anomalous cosmic rays. Examples include recent observations

What Are the Sources of Solar Energetic Particles? Element Abundances and Source Plasma Temperatures [PDF]

open access: yes, 2015
We have spent 50 years in heated discussion over which populations of solar energetic particles (SEPs) are accelerated at flares and which by shock waves driven out from the Sun by coronal mass ejections (CMEs). The association of the large “gradual” SEP
