Measuring the Plasma Density of a Ferroelectric Plasma Source in an Expanding Plasma [PDF]

open access: yesJournal of Applied Physics, 2003
The initial density and electron temperature at the surface of a ferroelectric plasma source were deduced from floating probe measurements in an expanding plasma. The method exploits negative charging of the floating probe capacitance by fast flows before the expanding plasma reaches the probe.

The Plasma Universe [PDF]

open access: yesSymposium - International Astronomical Union, 1990
The term “Plasma Universe”, coined by Hannes Alfvén, emphasizes the fact that plasma phenomena discovered in the laboratory and in accessible regions of space, must be important also in the rest of the universe, which consists almost entirely of matter in the plasma state.Relevant aspects of this concept will be discussed.

Simulation of Plasma Emission in Magnetized Plasmas

open access: yesThe Astrophysical Journal, 2022
Abstract The recent Parker Solar Probe observations of type III radio bursts show that the effects of the finite background magnetic field can be an important factor in the interpretation of data. In the present paper, the effects of the background magnetic field on the plasma-emission process, which is believed to be the main emission ...

Streaming Instability Generation in Lunar Plasma Environment [PDF]

open access: yesarXiv, 2023
Plasma instabilities are the non-linear processes occurring in plasmas when excess energy gets accumulated in a plasma system which is unable to hold it. There are almost 60 known plasma instabilities in nature.

Hydrogen-, Helium-, and Lithium-like Bound States in Classical and Quantum Plasmas

open access: yesPlasma, 2022
We study the effective interactions and the mass action constants for pair and triple associations in classical and quantum plasmas. Avoiding double counting, we derive new expressions for the mass action constants.

Plasma optics improving plasma accelerators

open access: yesLight: Science & Applications, 2022
AbstractPlasma accelerators driven by high-power lasers can provide high-energy electron beams on a dramatically smaller scale than conventional radio-frequency accelerators. However, the performance of these accelerators is fundamentally limited by the diffraction of the laser.

Laser–Plasma Wake Velocity Control by Multi-Mode Beatwave Excitation in a Channel

open access: yesPlasma, 2023
The phase velocity of a laser-driven wakefield can be efficiently controlled in a plasma channel. A beatwave of two long laser pulses is used. The frequency difference between these two laser pulses equals the local plasma frequency, so that the slow ...

Pulsed Plasma Accelerator

open access: yesPlasma, 2023
In this paper, we consider the acceleration of plasma fluxes in crossed electromagnetic fields. The possible technical approach to a prospective plasma accelerator is discussed.

Understanding the Role of Plasma Bullet Currents in Heating Skin to Mitigate Risks of Thermal Damage Caused by Low-Temperature Atmospheric-Pressure Plasma Jets

open access: yesPlasma, 2023
Low-temperature atmospheric-pressure plasma jets are generally considered a safe medical technology with no significant long-term side effects in clinical studies reported to date.

Spatial Distribution Analyses of Axially Long Plasmas under a Multi-Cusp Magnetic Field Using a Kinetic Particle Simulation Code KEIO-MARC

open access: yesPlasma
To realize the development of a long plasma source with a uniform electron density distribution in the axial direction, the spatial distribution of plasma under a multi-cusp magnetic field was analyzed using a KEIO-MARC code.
