Observational evidence of accelerating electron holes and their effects on passing ions

open access: yesNature Communications, 2023
As a universal structure in space plasma, electron holes represent an obvious signature of nonlinear process. Although the theory has a 60-year history, whether electron hole can finally accelerate ambient electrons (or ions) is quite controversial ...

Acceleration radiation for orbiting electrons [PDF]

open access: yesPhysics Reports, 1998
This paper presents an analysis of the radiation seen by an observer in circular acceleration, for a magnetic spin. This is applied to an electron in a storage ring, and the subtilty of the interaction of the spin with the spatial motion of the electron is explicated.

A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

open access: yes, 2010
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

Acceleration of electrons at a curved shock [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 1994
AbstractThe paper deals with the acceleration of electrons at a nearly perpendicular curved shock wave and results are compared with the case of a plane shock wave. We formulate the equations of motion of an electron in adiabatic approximation and solve them in a special case.

Coordinated optical and radar observations of ionospheric pumping for a frequency pass through the second electron gyroharmonic at HAARP [PDF]

open access: yes, 2007
On 4 February 2005, the High-frequency Active Auroral Research Program (HAARP) facility was operated in O and X mode while pointing into the magnetic zenith to produce artificial optical emissions in the ionospheric F layer. The pump frequency was set to

Nanoplasmonic electron acceleration in silver clusters studied by angular-resolved electron spectroscopy

open access: yesNew Journal of Physics, 2012
The nanoplasmonic field enhancement effects in the energetic electron emission from few-nm-sized silver clusters exposed to intense femtosecond dual pulses are investigated by high-resolution double differential electron spectroscopy.

Electron Acceleration in Supernovae and Millimeter Perspectives

open access: yesActa Polytechnica CTU Proceedings, 2014
Supernovae launch a strong shock wave by the interaction of the expanding ejecta and surrounding circumstellar matter (CSM). At the shock, electrons are accelerated to relativistic speed, creating observed synchrotron emissions in radio wavelengths.
