Abstract
In contrast to the shape of the detonation wave in the normal shaped charge, a plane wave generator is used to transform a detonation wave from concentric circles to a flat wave. The construction of a plane wave generator consists of the combination of two high explosives of different V.O.D.'s, which when detonated in a certain manner will cause the detonation wave to reach all points at the bottom of the charge at the same time. In order to test the performance of the plane wave generator it is therefore necessary to monitor the final shape of the detonation wave. This can be done by the use of multi streak photography at very fast writing speeds, through an open iris. The streak writing speeds used in these experiments were 11Ons/mm and 56,8ns/mm. The ideal air gap between the column of explosives and plexiglass, which is used to mask the detonation, has also been researched at length and will be discussed in this paper.
