Team led graduate student PPPL produces unique magnetic reconnection
2017/9/20
Jonathan Ng, a Princeton University graduate student at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), has for the first time applied a fluid simulation to the space...
Fast-ignition design transport studies: realistic electron source, integrated PIC-hydrodynamics, imposed magnetic fields
Fast-ignition design transport realistic electron source integrated PIC-hydrodynamics imposed magnetic fields
2012/5/29
Transport modeling of idealized, cone-guided fast ignition targets indicates the severe challenge posed by fast-electron source divergence. The hybrid particle-in-cell [PIC] code Zuma is run in tandem...
An exact solution of the moving boundary problem for the relativistic plasma expansion in a dipole magnetic field
exact solution of the moving boundary problem relativistic plasma expansion dipole magnetic field Plasma Physics
2012/4/19
An exact analytic solution is obtained for a uniformly expanding, neutral, highly conducting plasma sphere in an external dipole magnetic field with an arbitrary orientation of the dipole moment in th...
Magnetic moment non-conservation in magnetohydrodynamic turbulence models
Magnetic moment non-conservation magnetohydrodynamic turbulence models Plasma Physics
2012/4/19
The fundamental assumptions of the adiabatic theory do not apply in presence of sharp field gradients as well as in presence of well developed magnetohydrodynamic turbulence. For this reason in such c...
A Generalized Flux Function for Three-dimensional Magnetic Reconnection
Generalized Flux Function Three-dimensional Magnetic Reconnection Plasma Physics
2011/8/2
Abstract: The definition and measurement of magnetic reconnection in three-dimensional magnetic fields with multiple reconnection sites is a challenging problem, particularly in fields lacking null po...
Self-similar analytical model of the plasma expansion in a magnetic field
Plasma expansion Self-similar model Magnetic field Plasma Physics
2011/8/2
Abstract: The study of hot plasma expansion in a magnetic field is of interest for many astrophysical applications. In order to observe this process in laboratory, an experiment is proposed in which a...
Assessment of hydrocarbon electron-impact ionization cross section measurements for magnetic fusion
electron-impact ionization cross section magnetic fusion
2011/9/9
Partial ionization cross section experiments have been carried out recently at the University of Innsbruck for three types of hydrocarbons, i.e. acetylene, ethylene and propene. Cross section data ts...
Radiative diagnostics for sub-Larmor scale magnetic turbulence
Radiative diagnostics sub-Larmor scale magnetic turbulence
2011/9/6
Radiative diagnostics of high-energy density plasmas is addressed in this paper. We propose that the radiation produced by energetic particles in small-scale magnetic field turbulence, which can occur...
Robustness of the filamentation instability as shock mediator in arbitrarily oriented magnetic field
Robustness of the filamentation arbitrarily oriented magnetic field
2011/9/14
The filamentation instability (sometimes also referred to as “Weibel”) is a key process in many astrophysical scenario. In the Fireball model for Gamma Ray Bursts, this instability is believed to medi...
A model of driven and decaying magnetic turbulence in a cylinder
model Driven field-aligned currents
2011/8/30
Using mean-field theory, we compute the evolution of the magnetic field in a cylinder with outer perfectly conducting boundaries, an imposed axial magnetic and electric field. The thus injected magnet...
