Geometrical effects of exploding film on plasma formation

Metallized polypropylene films (MPPF) can serve as an alternate for exploding wires in many applications. Compared to wires, MPPF is more structurally robust and can be shaped more easily for specific applications. If long films are desired, the film can be shaped to fit a variety of geometries. In our experiments, MPPF as along as 13″ have exhibited plasma formation. Experiments were performed to analyze the effect of the geometry of the film, and its orientation on transient plasma formation. Tests with flat geometries and semi-circular geometries were conducted. The results have been analyzed and are presented.
