Abstract :
The plasma bubble formed by a radial wire array with an extended cathode is viewed by an extreme-ultraviolet imaging system. The wire array setup, which has similarities to a plasma focus, leads to the acceleration of the bubble along the cathode stalk. The images show the evolution of the bubble as it propagates along the stalk and then stagnates on the axis.
