Association of cusp energetic ions with geomagnetic storms and substorms [PDF]

open access: yesAnnales Geophysicae, 2012
Energetic ions observed in the cusp have been explained as a result of processes within the magnetosphere, but also proposed as a driver of some of those same processes. This study assesses potential connections between energetic ions observed in the

Pluto's Interaction With Energetic Heliospheric Ions [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2019
AbstractPluto energies of a few kiloelectron volts and suprathermal ions with tens of kiloelectron volts and above. We measure this population using the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) instrument on board the New Horizons spacecraft that flew by Pluto in 2015. Even though the measured ions have gyroradii larger than

Density and temperature of energetic electrons in the Earth's magnetotail derived from high-latitude GPS observations during the declining phase of the solar cycle [PDF]

open access: yes, 2011
Single relativistic-Maxwellian fits are made to high-latitude GPS-satellite observations of energetic electrons for the period January 2006-November 2010; a constellation of 12 GPS space vehicles provides the observations. The derived fit parameters (for

Resonant coupling of ion-cyclotron waves to energetic helium ions

open access: yesPhysical Review Letters, 1994
First measurements were performed to test a model prediction which states that the off axis coupling of ion-cyclotron waves to energetic helium ions can generate either an inward or an outward drift of these particles. Ion-cyclotron waves with a power of up to 1 MW are coupled to energetic particles at the high field side, the low field side, or in the

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.

The measurements of light high-energy ions in NINA-2 experiment [PDF]

open access: yesAnnales Geophysicae, 2007
The flux of energetic light ions at low altitude is both an important input and output for self-consistent calculations of albedo particles resulting from the interaction of trapped and cosmic ray particles, with the upper atmosphere.

EISCAT/CRRES observations: Nightside ionospheric ion outflow and oxygen-rich substorm injections [PDF]

open access: yes, 1996
We present combined observations made near midnight by the EISCAT radar, all-sky cameras and the combined released and radiation efects satellite (CRRES) shortly before and during a substorm.

Radial dependence of foreshock cavities: a case study [PDF]

open access: yesAnnales Geophysicae, 2004
We present a case study of Geotail, Interball-1, IMP-8, and Wind observations of density and magnetic field strength cavities excavated by the enhanced pressures associated with bursts of energetic ions in the foreshock.

Ultra-Low Power Consuming Direct Radiation Sensors Based on Floating Gate Structures

open access: yesJournal of Low Power Electronics and Applications, 2017
In this paper, we report on ultra-low power consuming single poly floating gate direct radiation sensors. The developed devices are intended for total ionizing dose (TID) measurements and fabricated in a standard CMOS process flow.

Properties of energetic-particle continuum modes destabilized by energetic ions with beam-like velocity distributions [PDF]

open access: yes, 2006
Properties of energetic-particle continuum modes (EPMs) destabilized by energetic ions in tokamak plasmas were investigated using a hybrid simulation code for magnetohydrodynamics and energetic particles.
