An energetic variational approach for ion transport [PDF]

open access: yesCommunications in Mathematical Sciences, 2014
The transport and distribution of charged particles are crucial in the study of many physical and biological problems. In this paper, we employ an Energy Variational Approach to derive the coupled Poisson-Nernst-Planck-Navier-Stokes system. All physics is included in the choices of corresponding energy law and kinematic transport of particles.

Monte Carlo Study of Imaging Plate Response to Laser-Driven Aluminum Ion Beams

open access: yesApplied Sciences, 2021
We measured the response of BAS-TR imaging plate (IP) to energetic aluminum ions up to 222 MeV, and compared it with predictions from a Monte Carlo simulation code using two different IP response models.

Parker Solar Probe Encounters the Leg of a Coronal Mass Ejection at 14 Solar Radii

open access: yesThe Astrophysical Journal, 2023
We use Parker Solar Probe (PSP) observations to report the first direct measurements of the particle and field environments while crossing the leg of a coronal mass ejection (CME) very close to the Sun (∼14 Rs).

Synthesis of AgN5 and its extended 3D energetic framework

open access: yesNature Communications, 2018
The pentazolate anion shows great promise for high energy density materials, but has only been isolated alongside non-energetic counter ions that impede its energetic properties.

Downward ion acceleration at auroral latitudes: cause of parallel electric field [PDF]

open access: yesAnnales Geophysicae, 2002
Observations with the Freja satellite at about 1700 km altitude of downward accelerated ions in the keV and sub-keV energy range are described and analysed.

Magnetospheric response to solar wind forcing: ultra-low-frequency wave–particle interaction perspective [PDF]

open access: yesAnnales Geophysicae, 2022
Solar wind forcing, e.g., interplanetary shock and/or solar wind dynamic pressure pulses impacting Earth's magnetosphere, manifests many fundamental important space physics phenomena, including producing electromagnetic waves, plasma heating, and ...

Acceleration of oxygen ions in the dynamic magnetotail [PDF]

open access: yesAnnales Geophysicae, 2004
The substorm-related acceleration and flux increases of energetic oxygen ions are studied on the basis of test particle orbits in the fields obtained from an MHD simulation of plasmoid formation and ejection and the collapse (dipolarization) of the ...

Effect of energetic electrons on transcritical bifurcation of low-frequency electrostatic waves in plasma [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2022
This paper studies the bifurcation types and phase portrait properties of ion-acoustic traveling waves in a plasma comprising warm adiabatic ions and energetic electrons with a nonthermal distribution function. A dynamical system is first derived for the

Effect of Trapped Energetic Ions on MHD Activity in Spherical Tori [PDF]

open access: yes, 2002
It is shown that the increase of beta (the ratio of plasma pressure to the magnetic field pressure) may change the character of the influence of trapped energetic ions on MHD stability in spherical tori.
