Abstract

A spectroscopic technique for continuous and time-resolved study of the atomic and molecular species produced by electrically exploded wires is described. A high-speed drum camera is utilized to record the time history of the explosion spectrum. More detailed studies (from photographic plates) of the spectrum at selected times are then conducted by use of a rotating shutter. Results are presented from experiments with aluminum wires exploded in various controlled atmospheres.
