The initial current flow in single and double wire loads exploded by current generators with dI/dt in the range of 1010–1012 A/s has been investigated using laser absorption and interferometric techniques. The results clearly show heterogeneous cur

Plasma dynamics are characterized in a long‐conduction time plasma opening switch [Phys. Fluids B 4, 2368 (1992)] operated with densities and currents near the theoretical intersection of the magnetohydrodynamic (MHD) [IEEE Trans. Plasma Sci. PS‐

A nonresonant laser absorption technique is described for studying the density and temperature profiles in a high density z‐pinch discharge. A long pulse (700‐ns) dye laser backlights the pinch and a streak camera records the transmitted laser in
