Abstract :
End-On interferometric measurements of the areal electron density distribution of wire array z-pinches has revealed striking differences in the behaviour of ablation plasmas. A change in wire material from aluminium to tungsten results in a change from a highly collisional structure dominated by shock formations to a much less collisional regime.
