Extreme Electron Acceleration with Fixed Radiation Energy [PDF]

Entropy, 2022
We examine the extreme situation of radiation from an electron that is asymptotically accelerated to the speed of light, resulting in finite emission energy.

Compound electron acceleration at planetary foreshocks [PDF]

Nature Communications
Shock waves, the interface of supersonic and subsonic plasma flows, are the primary region for charged particle acceleration in multiple space plasma systems, including Earth’s bow shock, which is readily accessible for in-situ measurements.

Ensemble Modeling of Radiation Belt Electron Acceleration by Chorus Waves: Dependence on Key Input Parameters

Space Weather, 2023
We perform ensemble simulations of radiation belt electron acceleration using the quasi‐linear approach during the storm on 9 October 2012, where chorus waves dominated electron acceleration at L = 5.2.

Electron Acceleration at Earth's Bow Shock Due to Stochastic Shock Drift Acceleration

Geophysical Research Letters
We use the Magnetospheric Multiscale mission (MMS) to study electron acceleration at Earth's quasi‐perpendicular bow shock to address the long‐standing electron injection problem.

Upper Limit of Outer Belt Electron Acceleration and Their Controlling Geomagnetic Conditions: A Comparison of Storm and Non‐Storm Events

Geophysical Research Letters
We perform a comprehensive investigation of the statistical distribution of outer belt electron acceleration events over energies from 300 keV to ∼10 MeV regardless of storm activity using 6‐years of observations from Van Allen Probes.

ELECTRONS AS ACCELERATED THERMOMETERS [PDF]

Nuclear Physics B, 1983
The possibility of using accelerated electrons to exhibit the quantum field theoretic relation between acceleration and temperature is considered. In principle, the depolarization of electrons in a magnetic field could be used to give temperature reading.

SiC Measurements of Electron Energy by fs Laser Irradiation of Thin Foils

Micromachines, 2023
SiC detectors based on a Schottky junction represent useful devices to characterize fast laser-generated plasmas. High-intensity fs lasers have been used to irradiate thin foils and to characterize the produced accelerated electrons and ions in the ...

RF acceleration of ultracold electron bunches

Structural Dynamics, 2023
The ultrafast and ultracold electron source, based on laser cooling and trapping of atomic gas and its subsequent near-threshold two-step photoionization, is capable of generating electron bunches with a high transverse brightness at energies of roughly ...

MMS Observation of Two‐Step Electron Acceleration at Earth's Bow Shock

Geophysical Research Letters, 2023
We use the Magnetospheric Multiscale mission to observe a bi‐directional electron acceleration event in the electron foreshock upstream of Earth's quasi‐perpendicular collisionless bow shock.
