An Exploration of Heating Mechanisms in a Supra-arcade Plasma Sheet Formed after a Coronal Mass Ejection [PDF]

open access: yes, 2017
We perform a detailed analysis of the thermal structure of the region above the post-eruption arcade for a flare that occurred on 2011 October 22. During this event, a sheet of hot plasma is visible above the flare loops in the 131 Å bandpass of the ...

The VLF-induced ionospheric perturbations detected by DEMETER during solar minimum

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2023
The VLF-induced ionospheric heating events from the powerful transmitter NWC are collected at extremely low solar activity years of 2008–2009, and their spatial and temporal distribution features are investigated.

Solid superheating observed in two-dimensional strongly-coupled dusty plasma

open access: yes, 2008
It is demonstrated experimentally that strongly-coupled plasma exhibits solid superheating. A 2D suspension of microspheres in dusty plasma, initially self-organized in a solid lattice, was heated and then cooled rapidly by turning laser heating on and ...

Recent Observations of Plasma and Alfvenic Wave Energy Injection at the Base of the Fast Solar Wind

open access: yes, 2012
We take stock of recent observations that identify the episodic plasma heating and injection of Alfvenic energy at the base of fast solar wind (in coronal holes).

Long-term evolution of broken wakefields in finite radius plasmas

open access: yes, 2014
A novel effect of fast heating and charging a finite-radius plasma is discovered in the context of plasma wakefield acceleration. As the plasma wave breaks, the most of its energy is transferred to plasma electrons which create strong charge-separation ...

Coronal loop oscillations and diagnostics with Hinode/EIS [PDF]

open access: yes, 1974
Context.Standing slow (acoustic) waves commonly observed in hot coronal loops offer a unique opportunity to understand the properties of the coronal plasma. The lack of evidence for similar oscillations in cooler loops is still a puzzle.

Impact of two-close-frequency heating on ECR ion source plasma radio emission and stability

open access: yesPlasma Sources Science & Technology, 2019
Experiments have recently demonstrated that kinetic instabilities occurring in magnetoplasma are huge limiting factors to the flux of highly charged ion beams extracted from ECR ion sources. Recently, it has been shown that the two-frequency-heating (TFH)

On the challenge of plasma heating with the JET metallic wall [PDF]

open access: yes, 2013
The major aspects linked to the use of the JET auxiliary heating systems: NBI, ICRF and LHCD, in the new JET ITER-like wall are presented. We show that although there were issues related to the operation of each system, efficient and safe plasma heating ...

Iterative addition of parallel non-local effects to full wave ICRF finite element models in axisymmetric tokamak plasmas

open access: yesNuclear Fusion
The current response of a hot magnetized plasma to a radio-frequency wave is non-local, turning the electromagnetic wave equation into an integro-differential equation. Non-local physics gives rise to wave physics and absorption processes not observed in
