Beam physics studies for a high charge and high beam quality laser-plasma accelerator

Physical Review Accelerators and Beams
Electron acceleration by laser-plasma techniques is approaching maturity and is getting ready for the construction of particle accelerators with dedicated applications. We present a general methodology showing how beam physics studies can be used to achieve a specific parameter set in a laser-plasma accelerator.

Plasma-Related Atomic Physics with an Electron Beam Ion Trap

Plasma and Fusion Research, 2013
This paper reviews plasma-related atomic physics experiments performed with an electron beam ion trap (EBIT). In particular, activities with two types of EBITs at the University of Electro-Communications are reported after introducing the principle and the design of the devices. Spectroscopic and collisional data which are useful for plasma diagnostics,

Broadening of mm-wave beam by plasma turbulence in the basic plasma physics device TORPEX and TCV tokamak [PDF]

2019 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2019
Concerns have recently been raised about loss of efficiency in Neoclassical Tearing Modes (NTM) stabilization by Electron Cyclotron (EC) due to broadening of mm-wave beams interacting with plasma turbulence at the edge and the scrape-off layer (SOL) of tokamak plasmas.

Impurity Behavior in Plasma Recovery after a Vacuum Failure in the Experimental Advanced Superconducting Tokamak

Applied Sciences, 2023
After a vacuum failure in a tokamak, plasma runaway or plasma disruptions frequently occur during plasma recovery, causing difficulties in rebuilding a well-confined collisional plasma.

Fast calculations in nonlinear collective models of beam/plasma physics [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003
We consider an application of variational-wavelet approach to nonlinear collective models of beam/plasma physics: Vlasov/Boltzmann-like reduction from general BBGKY hierachy. We obtain fast convergent multiresolution representations for solutions which allow to consider polynomial and rational type of nonlinearities.

Physics of High-Charge Electron Beams in Laser-Plasma Wakefields [PDF]

Physical Review X, 2020
Laser wakefield acceleration (LWFA) and its particle-driven counterpart, particle or plasma wakefield acceleration (PWFA), are commonly treated as separate, though related, branches of high-gradient plasma-based acceleration. However, novel proposed schemes are increasingly residing at the interface of both concepts where the understanding of their ...

QUANTUM METHODOLOGIES IN BEAM, FLUID AND PLASMA PHYSICS [PDF]

New Aspects of Plasma Physics, 2008
The quantum methodologies useful for describing in a unified way several problems of nonlinear and collective dynamics of fluids, plasmas and beams are presented. In particular, the pictures given by the Madelung fluid and the Moyal-Ville-Wigner phase-space quasidistribution, including the related quantum tools such as marginal distributions for the ...
