Numerical modeling of laser-driven experiments aiming to demonstrate magnetic field amplification via turbulent dynamo
P. Tzeferacos, A. Rigby, A. Bott +29
The universe is permeated by magnetic fields, with strengths ranging from a femtogauss in the voids between the filaments of galaxy clusters to several teragauss in black holes and…
Transport of high-energy charged particles through spatially-intermittent turbulent magnetic fields
L. E. Chen, A. F. A. Bott, P. Tzeferacos +22
Identifying the sources of the highest energy cosmic rays requires understanding how they are deflected by the stochastic, spatially intermittent intergalactic magnetic field. Here…
Time-resolved fast turbulent dynamo in a laser plasma
A. F. A. Bott, P. Tzeferacos, L. Chen +25
Understanding magnetic-field generation and amplification in turbulent plasma is essential to account for observations of magnetic fields in the universe. A theoretical framework a…
Observation of magnetic field generation via the Weibel instability in interpenetrating plasma flows
C. M. Huntington, F. Fiuza, J. S. Ross +18
Collisionless shocks can be produced as a result of strong magnetic fields in a plasma flow, and therefore are common in many astrophysical systems. The Weibel instability is one c…
Insensitivity of a turbulent laser-plasma dynamo to initial conditions
A. F. A. Bott, L. Chen, P. Tzeferacos +18
It has recently been demonstrated experimentally that a turbulent plasma created by the collision of two inhomogeneous, asymmetric, weakly magnetised laser-produced plasma jets can…
Laboratory evidence of dynamo amplification of magnetic fields in a turbulent plasma
P. Tzeferacos, A. Rigby, A. Bott +27
Magnetic fields are ubiquitous in the Universe. Extragalactic disks, halos and clusters have consistently been shown, via diffuse radio-synchrotron emission and Faraday rotation me…
Strong suppression of heat conduction in a laboratory replica of galaxy-cluster turbulent plasmas
J. Meinecke, P. Tzeferacos, J. S. Ross +32
Galaxy clusters are filled with hot, diffuse X-ray emitting plasma, with a stochastically tangled magnetic field whose energy is close to equipartition with the energy of the turbu…
Numerical Simulation of magnetized jet creation using a hollow ring of laser beams
Y. Lu, P. Tzeferacos, E. Liang +11
Three dimensional FLASH magneto-hydrodynamics(MHD) modeling is carried out to interpret the OMEGA laser experiments of strongly magnetized, highly collimated jets driven by a ring…
Mega-Gauss Plasma Jet Creation Using a Ring of Laser Beams
L. Gao, E. Liang, Y. Lu +11
Using 20 OMEGA laser beams at the Laboratory for Laser Energetics, University of Rochester, to irradiate a flat plastic target in a hollow ring configuration, we created supersonic…
