Highly collimated, plasma-filled magnetic-flux tubes are frequently observed on galactic, stellar, and laboratory scales. We propose that a single, universal magnetohydrodynamic pumping process explains why such collimated, plasma-filled magnetic-flux tubes are ubiquitous. Experimental evidence from carefully diagnosed laboratory simulations of astrophysical jets confirms this assertion and is reported here. The magnetohydrodynamic process pumps plasma into a magnetic-flux tube and the…

Plasma tubes becoming collimated as a result of magnetohydrodynamic pumping
Collimated magnetized plasma structures are commonly observed on galactic, stellar, and laboratory scales. The Caltech plasma gun produces magnetically driven plasma jets bearing a striking
Magnetized and collimated millimeter scale plasma jets with astrophysical relevance
Magnetized collimated plasma jets are created in the laboratory to extend our understanding of plasma jet acceleration and collimation mechanisms with particular connection to astrophysical jets. In
Helical Shear-Flow Stabilization of an Astrophysically Relevant Laboratory Plasma Jet.
Observations from a new astrophysically relevant laboratory plasma jet experiment demonstrating the formation of long-lived, collimated, high aspect-ratio jets corroborate theoretical predictions that strong helical shear flows can stabilize current-driven instabilities in magnetically confined plasmas, solar prominences, and magnetically driven astrophysical jets in nature.
Measurements of Plasma Jets and Collimated Flux Tubes that are the Precursors of Spheromak Self-organization
A magnetized planar coaxial plasma gun is used to study the physics of spheromak formation. Eight magnetic flux tubes spanning from the cathode to the anode electrode are first filled with plasma by
Tendency of MHD Forces to Create Localized, Collimated Plasma-filled Flux Tubes & Ion Orbit Instability in a Flux Tube
Electrostatic helicity injection involves the injection of new azimuthal magnetic flux to link the existing axial flux of an open magnetic field. Since magnetic flux is frozen into plasma, this
Dynamics of Plasma Structures Interacting with External and Self-Generated Magnetic Fields
Plasmas interacting with external and self-generated magnetic fields often develop a long tubular structure of nearly uniform cross section. Such long collimated plasma tubes have been observed in a
Observation of kinetic plasma jets in a coronal-loop simulation experiment.
Analytic and numerical models show that these jets result from a particle orbit instability in a helical magnetic field whereby magnetic forces radially eject rather than confine ions with sufficiently large countercurrent axial velocity.
Magnetized plasma jets are generally modeled as magnetic flux tubes filled with flowing plasma governed by magnetohydrodynamics (MHD). We outline here a more fundamental approach based on flux tubes
Plasma Jet Studies via the Flow Z-Pinch
The ZaP sheared-flow Z-pinch produces high density Z-pinch plasmas that are stable for up to 2000 times the classical instability times. The presence of an embedded radial shear in the axial flow is

The astrophysical jet experiment at Caltech generates a T=2–5 eV, n=1021–1022 m−3 plasma jet using coplanar disk electrodes linked by a poloidal magnetic field. A 100 kA current generates a toroidal


A laboratory plasma experiment for studying magnetic dynamics of accretion discs and jets
This work describes a laboratory plasma experiment and initial results which should give insight into the magnetic dynamics of accretion discs and jets. A high-speed multiple-frame CCD camera reveals
Theory for explosive ideal magnetohydrodynamic instabilities in plasmas.
A single unifying nonlinear evolution equation describing such behavior in both astrophysical and tokamak plasmas is derived, which predicts that flux tubes rise explosively, narrow, and twist to pass through overlying magnetic field lines without reconnection.
Magnetohydrodynamic production of relativistic jets.
A magnetohydrodynamic model may explain the basic features of observed jets, including their speed and amount of collimation, and some of the details in the behavior and statistics of different jet-producing sources.
Suppose an electric current I flows along a magnetic flux tube that has poloidal flux psi and radius a = a(z), where z is the axial position along the flux tube. This current creates a toroidal
On why discs generate magnetic towers and collimate jets
We show that accretion discs with magnetic fields in them ought to make jets provided that their electrical conductivity prevents slippage and there is an ambient pressure in their surroundings. We
Three-dimensional magnetic field topology in a region of solar coronal heating
The observations reveal two magnetic features that characterize young active regions on the Sun: a set of rising magnetic loops and a tangential discontinuity of the magnetic field direction, the latter being the observational signature of an electric current sheet, providing strong support for coronal heating models based on the dissipation of magnetic energy at current sheets.
Experimental identification of the kink instability as a poloidal flux amplification mechanism for coaxial gun spheromak formation.
The magnetohydrodynamic kink instability is observed and identified experimentally as a poloidal flux amplification mechanism for coaxial gun spheromak formation, and the kink acts as a dynamo which converts toroidal toPoloidal flux.
