Transition Region Abundance Measurements During Impulsive Heating Events

open access: yes, 2015
It is well established that elemental abundances vary in the solar atmosphere and that this variation is organized by first ionization potential (FIP). Previous studies have shown that in the solar corona low-FIP elements, such as Fe, Si, Mg, and Ca, are

Capabilities of the ITER Electron Cyclotron Equatorial Launcher for Heating and Current Drive

open access: yesEPJ Web of Conferences, 2012
The ITER Electron Cyclotron Equatorial Launcher is designed to be one of the heating systems to assist and sustain the development of various ITER plasma scenarios starting with the very first plasma operation.

Acceleration of runaway electrons and Joule heating in solar flares [PDF]

open access: yes
The electric field acceleration of electrons out of a thermal plasma and the simultaneous Joule heating of the plasma are studied. Acceleration and heating timescales are derived and compared, and upper limits are obtained on the acceleration volume and ...

Stochastic Electron Acceleration by the Whistler Instability in a Growing Magnetic Field

open access: yes, 2017
We use 2D particle-in-cell (PIC) simulations to study the effect of the saturated whistler instability on the viscous heating and nonthermal acceleration of electrons in a shearing, collisionless plasma with a growing magnetic field, \textbf{B}.

Diagnosing the fast-heating process of the double-cone ignition scheme with X-ray spectroscopy

open access: yesHigh Power Laser Science and Engineering
In the double-cone ignition scheme of inertial confinement fusion, the head-on collision of two compressed fuel jets from the cone-tips forms an isochoric plasma, which is then heated suddenly by a MeV relativistic electron beam produced by ultra-intense

Interaction of a neutral cloud moving through a magnetized plasma [PDF]

open access: yes
Current collection by outgassing probes in motion relative to a magnetized plasma may be significantly affected by plasma processes that cause electron heating and cross field transport.

Fluctuating Polytropic Processes, Turbulence, and Heating

open access: yesThe Astrophysical Journal
This paper explores the thermodynamics of fluctuating polytropic processes and their connection to turbulence. It is shown that random fluctuations of polytropic processes produce a nonzero overall heating of a particle system, e.g., solar wind plasma ...
