COMPOSITION SUITABLE FOR A DEFLAGRATION TO DETONATION TRANSITION DEVICE

The present invention provides a composition of explosives, comprising: a first layer comprising a first thermally stable secondary explosive that is less sensitive than PETN explosive; a second layer comprising the first thermally stable secondary explosive; and a second thermally stable secondary explosive that is less sensitive than PETN explosive, where the first explosive is more sensitive than the second explosive, where the first explosive and the second explosive are mixed, and where the second layer contains effectively no primary explosive; a third layer of the second explosive packed and unmixed, where the second layer is disposed between the first layer and the third layer, where the first layer is in intimate contact with the second layer, and where the second layer is in intimate contact with the third layer.
