Collimated outflows (jets) are ubiquitous in the universe, appearing around sources as diverse as protostars and extragalactic supermassive black holes. Jets are thought to be magnetically collimated, and launched from a magnetized accretion disk surrounding a compact gravitating object. We have developed the first laboratory experiments to address time-dependent, episodic phenomena relevant to the poorly understood jet acceleration and collimation region. The experimental results show the periodic ejections of magnetic bubbles naturally evolving into a heterogeneous jet propagating inside a channel made of self-collimated magnetic cavities. The results provide a unique view of the possible transition from a relatively steady-state jet launching to the observed highly structured outflows.

We report on experiments in which magneticallydriven radiatively cooled plasma jets were produced by a1 MA, 250 ns current pulse on the MAGPIE pulsed powerfacility. The jets were driven by the pressure of a toroidalmagnetic field in a “magnetic tower” jet configuration. Thisscenario is characterized by the formation of a magneticallycollimated plasma jet on the axis of a magnetic “bubble”,confined by the ambient medium. The use of a radial metallicfoil instead of the radial wire arrays employed in our previouswork allows for the generation of episodic magnetictower outflows which emerge periodically on timescales of∼30 ns. The subsequent magnetic bubbles propagate withvelocities reaching ∼300 km/s and interact with previouseruptions leading to the formation of shocks.

Recent experiments performed at Imperial College on the pulsed-power magpie facility have successfully shown the formation of magnetically driven radiatively cooled plasma jets formed from radial wire arrays, which are relevant to the study of launching mechanisms in astrophysical jets. The experiments have been now extended to study the episodic ejection (∼ 25 ns) and the interaction of jets and magnetic bubbles with an ambient gas. The dynamics of the interaction is investigated through three-dimensional resistive magneto-hydrodynamic simulations using the code gorgon. Comparison with experiments is offered to validate the results. The ablation process as well as current reconnection is described and analyzed. The complex three-dimensional structure and the confinement/collimation effect offered by the magnetic field are investigated. The scenario is modified introducing a background gas (Ar, ρ ∼ 6.7 ×10-3 kg/m3), collimation effects are investigated for the new set-up.

We report on experiments in which magnetically driven radiatively cooled plasma jets were produced by a 1 MA, 250 ns current pulse on the MAGPIE pulsed power facility. The jets were driven by the pressure of a toroidal magnetic field in a “magnetic tower” jet configuration. This scenario is characterized by the formation of a magnetically collimated plasma jet on the axis of a magnetic cavity, confined by the ambient medium. The use of a radial metallic foil instead of the radial wire arrays employed in our previous work allows for the generation of episodic magnetic tower outflows which emerge periodically on timescales of ∼ 30 ns. The subsequent magnetic bubbles propagate with velocities reaching ∼ 300 km/s and interact with previous eruptions. This setup also allowed for the addition of a neutral gas above the foil in order to study the effect of the ambient density on the dynamics of both the early time hydrodynamic jet formed from plasma ablated from the foil and of the subsequent magnetic tower outflows.

The evolution of laboratory produced magnetic jets is followed numerically throughthree-dimensional, nonideal magnetohydrodynamic simulations. The experiments are designed tostudy the interaction of a purely toroidal field with an extended plasma background medium. Thesystem is observed to evolve into a structure consisting of an approximately cylindrical magneticcavity with an embedded magnetically confined jet on its axis. The supersonic expansion producesa shell of swept-up shocked plasma that surrounds and partially confines the magnetic tower.Currents initially flow along the walls of the cavity and in the jet but the development ofcurrent-driven instabilities leads to the disruption of the jet and a rearrangement of the field andcurrents. The top of the cavity breaks up, and a well-collimated, radiatively cooled, “clumpy” jetemerges from the system.
