jet with argon gas is presented. The jet is formed by ablation of an aluminum foil driven by a
1.4 MA, 250 ns current pulse in a radial foil Z-pinch configuration. The outflow consists of a
supersonic (Mach number∼ 3–5), dense (ion density ni∼ 10 18 cm− 3), highly collimated
(half-opening angle∼ 2− 5) jet surrounded by a lower density halo plasma moving with the
same axial velocity as the jet. The addition of argon above the foil leads to the formation of a …
