Physical mechanisms for the hydrodynamic beam-plasma instability

Soviet Physics Uspekhi, 1988
A quantitative study is made of the physical mechanisms responsible for the development of a collective hydrodynamic instability of a charged-particle beam in an isotropic plasma. The corresponding growth rate is calculated through an analysis of the dynamics of the motion of the beam particles in the field of their radiation. The coherence of the beam

Plasma physics with intense laser and ion beams

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2000
The unique combination of an intense heavy ion beam and a high-energy Nd:glass laser system at Gesellschaft f Schwerionenforschung (GSI-Darmstadt) facilitates pioneering beam-plasma interaction experiments and thus allows to address basic physics issues associated with heavy ion-driven inertial fusion.

Development of a Compact Plasma Trap for Experimental Beam Physics

Japanese Journal of Applied Physics, 2006
A tabletop experimental system has been developed for the study of various collective effects in space-charge-dominated beams. It is based on the recently proposed idea that the dynamic motion of a one-component plasma in a trap can be made physically equivalent to that of a charged-particle beam propagating through a linear transport channel.

High density plasma physics with heavy-ion beams

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
Abstract The accelerator facilities at GSI Darmstadt offer a unique possibility for experiments with heavy-ion-induced dense plasmas. Although the intensity of these heavy-ion beams is far below the regime of ICF, such beams are used to study basic physics, to develop diagnostic tools and special heavy-ion target designs.

Plasma-physical aspects of charged-particle beams

Physical Review A, 1981
Areas of interest for charged-particle beams are mentioned, and the classical beam concepts due to Alfv\'en, Lawson, and Bennett are described. From the equation of plasma mass transport the virial theorem of plasma physics is derived and evaluated for rotationally symmetric configurations so as to apply to long particle beams of nonrelativistic plasma

Electron-beam/plasma coupling physics in support of active experiments in space

2021 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2021
The recent development of compact, relativistic electron accelerators [1] might open up a new era of active experiments in space, driven by important scientific and national security applications [2] . Examples include using electron beams to trace magnetic field lines and establish causality between physical processes occurring in the magnetosphere ...

Diagnostic Neutral Beam Injectors for Large Plasma Physics Experiments

Fusion Technology, 1999
Low-divergent, quasi-stationary neutral beams are often applied in modern magnetic fusion devices as a diagnostic tool providing unique information about plasma parameters. The most important requirements to these beams are sufficiently large current and energy of the particles, so that the beam could penetrate to plasma core.

Electron-beam physical vapor deposition with decreasing plasma density

2021 IEEE International Conference on Advances in Electrical Engineering and Computer Applications (AEECA), 2021
In this paper, through an in-depth analysis and study of electron-beam physical vapor deposition accompanied by a decrease in plasma density, it has many interesting features compared to atmospheric plasma spraying (APS), including non-linear observation of deposition, high deposition rate, and microstructural flexibility, with the results show that a ...

Physics of ion beam plasma and problems of intensive ion beam transportation (invited) (abstract)

Review of Scientific Instruments, 1996
Studies considering the problem of intensive ion beam transportation on large distances are performed in the Institute of Physics, including three main aspects: (1) space charge compensation of a stationary steady state beam, (2) dynamic decompensation of a beam space charge resulting from the current modulation owing to ion source plasma instabilities,
