Recording of transient phenomena using a streak camera and a high-explosive driven flash

A new method to take frame sequences of a transient event by means of a simple streak camera is described. The camera, without slit, records light pulses which are generated by a detonation shock in a series of very narrow argon chambers as used for taking shadowgraphs. Frame rates are of the order of 1 MHz and exposure times below 10 nsec. A series of pictures of a shaped charge jet after perforating a steel plate was made using this equipment.
