    "abstract": "Highly collimated, plasma-filled magnetic flux tubes are frequently observed\non galactic, stellar and laboratory scales. We propose that a single, universal\nmagnetohydrodynamic pumping process explains why such collimated, plasma-filled\nmagnetic flux tubes are ubiquitous. Experimental evidence from carefully\ndiagnosed laboratory simulations of astrophysical jets confirms this assertion\nand is reported here. The magnetohydrodynamic process pumps plasma into a\nmagnetic flux tube and the stagnation of the resulting flow causes this flux\ntube to become collimated.",
