Particle Acceleration Mechanisms [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
AbstractHigh-energy particle acceleration is observed to proceed in a diverse variety of astrophysical sites ranging from the terrestrial aurorae to the most distant quasars. Particle acceleration is a fairly common channel for the release of large-scale kinetic, rotational, and magnetic energy.

Safety for particle accelerators [PDF]

open access: yes, 2021
The use of non-standard technologies such as superconductivity, cryogenics and radiofrequency pose challenges for the safe operation of accelerator facilities that cannot be addressed using only best practice from occupational safety in conventional ...

Discussion on Rayleigh equation obtained for a Hall thruster plasma with dust

open access: yesJournal of Theoretical and Applied Physics, 2018
The present study focuses on the Rayleigh equation derived in the case of a Hall thruster plasma having dust contamination, produced near the exit of the channel due to the finite divergence of the accelerated ions and the sputtering of the walls. In the

Resonant third harmonic generation of super-Gaussian laser beam in a rippled density plasma

open access: yesJournal of Theoretical and Applied Physics, 2018
Resonant third harmonic generation of super-Gaussian laser beam in rippled density plasma is studied. Both the relativistic and ponderomotive nonlinearities are included in the analysis, and the study is done for self-guided laser beam.

Additional acceleration of solar-wind particles in current sheets of the heliosphere [PDF]

open access: yes, 2015
Particles of fast solar wind in the vicinity of the heliospheric current sheet (HCS) or in a front of interplanetary coronal mass ejections (ICMEs) often reveal very peculiar energy or velocity profiles, density distributions with double or triple peaks,

Vertical evolution of auroral acceleration at substorm onset [PDF]

open access: yes, 2009
This study describes the onset process of auroral substorms in connection with the vertical evolution of auroral particle acceleration, on the basis of auroral kilometric radiation (AKR) dynamics.

Generation of quasi-monoenergetic protons from thin multi-ion foils by a combination of laser radiation pressure acceleration and shielded Coulomb repulsion [PDF]

open access: yes, 2013
We study theoretically and numerically the acceleration of protons by a combination of laser radiation pressure acceleration and Coulomb repulsion of carbon ions in a multi-ion thin foil made of carbon and hydrogen.

Effect of dust on tilted electrostatic resistive instability in a Hall thruster

open access: yesJournal of Theoretical and Applied Physics, 2018
Effect of negatively charged dust on resistive instability corresponding to the electrostatic wave is investigated in a Hall thruster plasma when this purely azimuthal wave is tilted and strong axial component of wave vector is developed.

Particle Acceleration and Their Escape into the Heliosphere in Solar Flares with Open Magnetic Field

open access: yesThe Astrophysical Journal, 2023
Energetic particle populations in the solar corona and in the heliosphere appear to have different characteristics even when produced in the same solar flare.
