ECF is a state of the art facility for design and testing of energetic materials and components. Two key elements are the flash x-ray machines: a 6-head 150 keV, and a 6-head 300-keV instrument. The 150 keV system was used to study the action and reaction of a linear shaped charge (LSC) while submerged in water; the submerged samples were viewed from the top to capture the interaction of one piece with another piece nearby. Each LSC was covered by separate rubber coverings and affixed to a composite plate. Three heads, delayed by a specified time, were used to capture …

Description
ECF is a state of the art facility for design and testing of energetic materials and components. Two key elements are the flash x-ray machines: a 6-head 150 keV, and a 6-head 300-keV instrument. The 150 keV system was used to study the action and reaction of a linear shaped charge (LSC) while submerged in water; the submerged samples were viewed from the top to capture the interaction of one piece with another piece nearby. Each LSC was covered by separate rubber coverings and affixed to a composite plate. Three heads, delayed by a specified time, were used to capture the time sequence. Side views were done with and without the rubber coverings to examine the dampening effect of the cover. An end-on perspective was also captured by x-ray using one head and several time delays. Debris scatter from a larger device was also examined. Explosive used was in a pellet form initiated by a detonator and a timing lead. The x-ray radiographs show the particles from this device as they expand outward. Three x-ray source tubes were used in a large horizontal array, apertured to expose individual pieces of film. Another x-ray source was placed overhead and simultaneously exposed a film under the object.
