Title: Velocimetry studies on the prompt initiation of PBX 9502

Conference ·
OSTI ID:10178598

In this paper, a description is given for the extension and refinement of the methods used for the investigation of the reaction-rate evolution in the prompt initiation of PBX9502 (95 wt percent TATB/5 wt percent Kel F 800). A further improvement was realized in the experimental configuration of 9SD, which already was sufficient to resolve considerable detail in the detonation reaction zones. In this study, the interface velocity histories where obtained on specimens with thicknesses less that the approximately 3-mm run distance needed to establish a nearly steady detonation reaction zone with the driving system. Within this experimental range, an initally rounded character was observed in velocity histories, and the quantitative measurements of the evolution of this feature during the prompt initiation buildup process provide the significant new experimental information of this paper.
