Particle acceleration by twisted laser beams

open access: yesFrontiers in Physics, 2022
We consider particle acceleration in plasmas, using twisted laser beams, or beams with orbital angular momentum. We discuss different acceleration processes using two LG laser modes, which include donut wakefield, beat-wave and self-torque acceleration ...

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]

open access: yes, 2012
We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Small amplitude dust acoustic solitary wave in magnetized two ion temperature plasma

open access: yesJournal of Taibah University for Science, 2020
The characteristics of obliquely propagating dust acoustic solitary wave in magnetized dusty plasma are analysed by considering the plasma to have electrons, two-temperature ions and massive dust grains with heavy charge.

Laser Particle Acceleration

open access: yesConference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
The production of highly energetic beams of both electrons and ions is a major part of the experimental programme at the Central Laser Facility (CLF), STFC Rutherford Appleton Laboratory. Every year sees a significant number of experiments done in both areas. This has been complemented by theoretical studies that have been carried out at the CLF and UK

Adaptive particle swarm optimization [PDF]

open access: yes, 2009
An adaptive particle swarm optimization (APSO) that features better search efficiency than classical particle swarm optimization (PSO) is presented. More importantly, it can perform a global search over the entire search space with faster convergence ...

Polarized Beam Dynamics and Instrumentation in Particle Accelerators [PDF]

open access: yes, 2023
This Open Access book is drawn from lectures dispensed at the U.S. Particle Accelerator School (USPAS) Summer 2021 Spin Class, by experts in the field. It is an introduction to the dynamics of spin in charged particle accelerators, and to the accelerator

Particle acceleration in binaries

open access: yesEPJ Web of Conferences, 2017
Cygnus X-3 massive binary system is one of the powerful sources of radio and X-ray emission consisting of an accreting compact object, probably a black hole, with a Wolf-Rayet star companion.

Particle Acceleration Mechanisms

open access: yesSpace Science Reviews, 2008
We review the possible mechanisms for production of non-thermal electrons which are responsible for non-thermal radiation in clusters of galaxies. Our primary focus is on non-thermal Bremsstrahlung and inverse Compton scattering, that produce hard X-ray emission.

Acceleration in turbulent channel flow [PDF]

open access: yes, 2010
We use Direct Numerical Simulations of turbulent channel flow to study the acceleration A corresponding to the full fluid velocity u and the acceleration a corresponding to the fluctuating velocity u? ? u?hui where hui is the mean flow.

Growth of Rayleigh instability in a Hall thruster channel having dust in exit region

open access: yesAIP Advances, 2019
In a Hall thruster, the axial movement of ions towards the exit of the chamber and the divergence of ion beam sputter the wall and thus the maximum erosion of wall of the exit region takes place.
