Andrea Ciardi,Sergey Lebedev,Adam Frank,Eric G. Blackman,J. P. Chittenden,C. J. Jennings,D. J. Ampleford,S. N. Bland,S. C. Bott,J. Rapley,Gareth Hall,Francisco Suzuki-Vidal,Alberto Marocchino,Thibaut Lery,Chantal Stehlé +14 more
TL;DR: In this article, the evolution of laboratory produced magnetic jets is followed numerically through three-dimensional, nonideal magnetohydrodynamic simulations, designed to study the interaction of a purely toroidal field with an extended plasma background medium, and the system is observed to evolve into a structure consisting of an approximately cylindrical magnetic cavity with an embedded magnetically confined jet on its axis.

Sergey Lebedev,Andrea Ciardi,D. J. Ampleford,Simon Bland,S. C. Bott,J. P. Chittenden,Gareth Hall,J. Rapley,Adam Frank,Eric G. Blackman,Thibaut Lery +10 more
TL;DR: In this paper, the MAGPIE pulsed power machine was used to explore the role of magnetic pressure in creating and collimating the outflow as well as showing the creation of a central jet within the broader outflow cavity.

TL;DR: The 80-TW "Z" pulsed power facility at Sandia National Laboratories as discussed by the authors is the largest pulsed-power device in the world today, and it can discharge up to 22'MJ of energy stored in its capacitor banks into a current pulse that rises in 100'ns and peaks at a current as high as 30 MA in low-inductance cylindrical targets.

Jet Deflection via Cross winds: Laboratory Astrophysical Studies
Sergey Lebedev,D. J. Ampleford,Andrea Ciardi,Simon Bland,J. P. Chittenden,M. G. Haines,Adam Frank,Eric G. Blackman,Andrew J. Cunningham +8 more
TL;DR: In this paper, the authors present new data from High Energy Density (HED) laboratory experiments designed to explore the interaction of a heavy hypersonic radiative jet with a cross wind, showing that the jets are deflected by the action of the cross wind with the angle of deflection dependent on the proximity of the foil.
