Thermo-magneto coupling in a dipole plasma

, 2012
On a dipole plasma, we observe the generation of magnetic moment, as the movement of the levitating magnet-plasma compound, in response to electron-cyclotron heating and the increase of $\beta$ (magnetically-confined thermal energy).

Constraints on ion versus electron heating by plasma turbulence at low beta [PDF]

Journal of Plasma Physics, 2018
It is shown that in low-beta, weakly collisional plasmas, such as the solar corona, some instances of the solar wind, the aurora, inner regions of accretion discs, their coronae and some laboratory plasmas, Alfvénic fluctuations produce no ion heating ...

Real-time capable modeling of ICRF heating on NSTX and WEST via machine learning approaches

Nuclear Fusion
A real-time capable core Ion Cyclotron Range of Frequencies (ICRF) heating model on NSTX and WEST is developed. The model is based on two nonlinear regression algorithms, the random forest ensemble of decision trees and the multilayer perceptron neural ...

Densification and preservation of ceramic nanocrystalline character by spark plasma sintering [PDF]

, 2012
Spark plasma sintering is a hot pressing technique where rapid heating by dc electric pulses is used simultaneously with applied pressure. Thus, spark plasma sintering is highly suitable for rapid densification of ceramic nanoparticles and preservation ...

Energy transfer, pressure tensor and heating of kinetic plasma [PDF]

, 2017
Kinetic plasma turbulence cascade spans multiple scales ranging from macroscopic fluid flow to sub-electron scales. Mechanisms that dissipate large scale energy, terminate the inertial range cascade and convert kinetic energy into heat are hotly debated.

Burning plasma achieved in inertial fusion

Nature, 2022
Obtaining a burning plasma is a critical step towards self-sustaining fusion energy1. A burning plasma is one in which the fusion reactions themselves are the primary source of heating in the plasma, which is necessary to sustain and propagate the burn ...

Estimates of Proton and Electron Heating Rates Extended to the Near-Sun Environment

The Astrophysical Journal Letters, 2023
A central problem of space plasma physics is how protons and electrons are heated in a turbulent, magnetized plasma. The differential heating of charged species due to dissipation of turbulent fluctuations plays a key role in solar wind evolution ...

Differential kinetic dynamics and heating of ions in the turbulent solar wind

New Journal of Physics, 2016
The solar wind plasma is a fully ionized and turbulent gas ejected by the outer layers of the solar corona at very high speed, mainly composed by protons and electrons, with a small percentage of helium nuclei and a significantly lower abundance of ...
