Turbulent dynamo in a collisionless plasma.
Magnetic fields pervade the entire universe and affect the formation and evolution of astrophysical systems from cosmological to planetary scales. The generation and dynamical amplification of extragalactic magnetic fields through cosmic times (up to microgauss levels reported in nearby galaxy clusters, near equipartition with kinetic energy of plasma motions, and on scales of at least tens of ...
متن کاملMagnetorotational Turbulence and Dynamo in a Collisionless Plasma.
We present results from the first 3D kinetic numerical simulation of magnetorotational turbulence and dynamo, using the local shearing-box model of a collisionless accretion disk. The kinetic magnetorotational instability grows from a subthermal magnetic field having zero net flux over the computational domain to generate self-sustained turbulence and outward angular-momentum transport. Signifi...
متن کاملTurbulent transport of trapped electron modes in collisionless magnetized plasma
Submitted for the APR09 Meeting of The American Physical Society Turbulent transport of trapped electron modes in collisionless magnetized plasma YONG XIAO, University of California, Irvine — A prominent candidate for the electron heat transport in high temperature toroidal plasmas is collisionless trapped electron mode (CTEM) turbulence. Our large scale simulations of CTEM turbulence using gyr...
متن کاملIntense Reb Transport in a Weakly Magnetized Plasma*
Intense relativistic electron beams (REBs) have been used in various applications for the purpose of high-power microwave (HPM) generation. By injecting the beam into a plasma, it is possible to overcome the space-charge limiting current because of charge and current neutralization provided by the plasma. Our goal in this experiment was to study beam transport issues which may be relevant to th...
متن کاملMagnetized Turbulent Dynamo in Protogalaxies
The prevailing theory for the origin of cosmic magnetic fields is that they have been amplified to their present values by the turbulent dynamo inductive action in the protogalactic and galactic medium. Up to now, in calculation of the turbulent dynamo, it has been customary to assume that there is no back reaction of the magnetic field on the turbulence, as long as the magnetic energy is less ...
