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

Electron Energy Spectrometer for MIR-THz FEL Light Source at Chiang Mai University
The linear accelerator system of the PBP-CMU Electron Linac Laboratory has been designed with the aim of generating free-electron lasers (FELs) in the mid-infrared (MIR) and terahertz (THz) regions.

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

Nonlinear physics and energetic particle transport features of the beam–plasma instability [PDF]
In this paper we study transport features of a one-dimensional beam–plasma system in the presence of multiple resonances. As a model description of the general problem of a warm energetic particle beam, we assume $n$ cold supra-thermal beams and investigate the self-consistent evolution in the presence of the complete spectrum of nearly degenerate ...
