Insights into nanoparticle shape transformation by energetic ions [PDF]

open access: yesScientific Reports, 2023
Shape modification of embedded nanoparticles can be achieved by means of swift heavy ion irradiation. During irradiation, the particles elongate and align with the direction of the ion beam, presumably due to nanometer-scale phase transitions induced by ...

Relating Energetic Ion Spectra to Energetic Neutral Atoms

open access: yesThe Astrophysical Journal, 2023
Heliospheric energetic neutral atoms (ENAs) originate from energetic ions that are neutralized by charge exchange with neutral atoms in the heliosheath and very local interstellar medium (VLISM).

Inverse energy dispersion of energetic ions observed in the magnetosheath

open access: yesGeophysical Research Letters, 2016
We present a case study of energetic ions observed by the Energetic Particle Detector (EPD) on the Magnetospheric Multiscale spacecraft in the magnetosheath just outside the subsolar magnetopause that occurred at 1000 UT on 8 December 2015.

Energetic ions scattered into the loss cone with observations of the Cluster satellite [PDF]

open access: yesAnnales Geophysicae, 2016
In this paper, we report in situ observations by the Cluster spacecraft of energetic ions scattered into the loss cone during the inbound pass from the plasma sheet into the plasmasphere.

Energetic Neutral Atom Imaging of the Earth’s Ring Current and Some Results from the Chinese Double Star Program

open access: yesMagnetochemistry, 2023
The ring current region in the Earth’s magnetosphere contains energetic charged particles, which are injected from the magnetotail, get trapped in the inner magnetosphere, and finally drift around the Earth.

Investigation of energetic ion losses induced by long-lived saturated internal mode with energetic particle diagnostics in the HL-2A tokamak

open access: yesNuclear Fusion, 2023
Several sets of energetic particle diagnostics, including a set of neutron flux monitoring systems, a solid-state neutral particle analyzer and a fast ion loss probe (FILP), have been used to investigate the energetic ion losses induced by the long-lived

Dynamical characteristics of magnetospheric energetic ion time series: evidence for low dimensional chaos [PDF]

open access: yesAnnales Geophysicae, 2003
This paper is a companion to the first work (Pavlos et al., 2003), which contains significant results concerning the dynamical characteristics of the magnetospheric energetic ions’ time series.

Modelling of energetic particle drive and damping effects on TAEs in AUG experiment with ECCD

open access: yesNuclear Fusion, 2023
The impact of electron cyclotron current drive (ECCD)-driven current on toroidicity-induced Alfvén eigenmodes (TAEs) in experiments on the AUG tokamak is investigated numerically. The dynamical evolution of the plasma profiles and equilibria are modelled

Hybrid-kinetic simulation of synergy between fishbone/sawtooth and tearing mode-induced energetic-ion transport in a tokamak plasma

open access: yesNuclear Fusion, 2023
The resonant interaction between $m/n = 2/1$ tearing mode (TM) and energetic ions redistributed by $m/n = 1/1$ fishbone/sawtooth collapse has been observed recently in HL-2A neutral beam injection-heated high-density plasmas, where m is the poloidal mode

Solar wind contribution to the average population of energetic He+ and He++ ions in the Earth's magnetosphere [PDF]

open access: yesAnnales Geophysicae, 1994
Measurements with the ion charge-energy-mass spectrometer CHEM on the AMPTE/CCE spacecraft were used to investigate the origin of energetic He+ and He++ ions observed in the equatorial plane at 3 ≤ L ≤ 9.
