Opening claim text (preview).
I claim: 1. A device, comprising: a housing having a proximal portion and a distal portion; a liner positioned at a distal end of the housing; a detonator positioned in the proximal portion of the housing; a first chamber, positioned in the distal portion of the housing, configured to contain an energetic material capable of superdetonation and which has a length sufficient to allow an input pressure wave to initiate a superdetonation wave produced by the energetic material and to allow the superdetonation wave to contact the liner prior to relaxation of the superdetonation wave to normal detonation pressure; a second chamber, positioned between the detonator and the first chamber, configured to contain an attenuator; and a third chamber, positioned between the detonator and the second chamber, configured to contain a booster material. 2. The device of claim 1 , in which the liner is sufficiently thin so as to be expelled from the device upon contact of the superdetonation wave produced by the energetic material. 3. The device of claim 1 , further comprising a homogenous energetic material capable of superdetonation contained within the first chamber. 4. The device of claim 1 , wherein the liner has a thickness ranging from 0.001 to 5 mm. 5. The device of claim 1 , wherein the liner has an outer perimeter having dimensions smaller than an outer perimeter of the housing. 6. A device, comprising: a housing having a proximal portion and a distal portion; a liner positioned at a distal end of the housing; a detonator positioned in the proximal portion of the housing; a homogeneous energetic material capable of superdetonation contained in a first chamber positioned in the distal portion of the housing, which first chamber has a length sufficient to allow an input pressure wave to initiate a superdetonation wave produced by the homogeneous energetic material and to allow the superdetonation wave to contact the liner prior to relaxation of the superdetonation wave to normal detonation pressure; a second chamber comprising an attenuator, wherein the second chamber is positioned between the detonator and the first chamber; and a third chamber comprising a booster material. 7. The device of claim 6 , in which the attenuator is capable of shaping an input pressure to initiate superdetonation of the homogeneous energetic material. 8. The device of claim 6 , in which the homogeneous energetic material comprises nitromethane, nitroglycerin, ethylene glycol dinitrate, pentaerythritol tetranitrate, erythritol tetranitrate, trinitrotoluene, or two or more thereof. 9. The device of claim 6 , in which the booster material comprises a homogeneous energetic material and an amine component. 10. The device of claim 9 , in which the amine component is an alkyl amine selected from diethylenetriamine (DETA), ethylenediamine (EDA), or a mixture thereof. 11. The device of claim 6 , wherein the device is used for improvised explosive device (IED) defeat, ordinance disposal, high-explosive anti-tank (HEAT) munitions, demolition, or a combination thereof. 12. A method of making a device, comprising: placing a homogeneous energetic material capable of superdetonation into a first chamber of a housing, wherein the first chamber is located in a distal portion of the housing and has a length that is sufficient to allow an input pressure wave to initiate a superdetonation wave produced by the homogeneous energetic material and to allow the superdetonation wave to contact the liner prior to relaxation of the superdetonation wave to normal detonation pressure; placing an attenuator into a second chamber of the housing; placing a booster material in a third chamber of the housing, wherein the third chamber is located in the proximal end of the housing; and placing a detonator in a proximal portion of the housing. 13. The method of claim 12 , further comprising placing a sensitizer component in the first chamber. 14. The method of claim 13 , wherein the sensitizer component comprises an amine component. 15. The method of claim 14 , wherein the amine component is an alkyl amine selected from diethylenetriamine (DETA), ethylenediamine (EDA), or a mixture thereof. 16. A method for projecting a liner, comprising superdetonating the homogeneous energetic material contained within the device of claim 6 , so as to project the liner at a flyer velocity from 30% higher to 140% higher than a flyer velocity produced by regular detonation of the same material. 17. The method of claim 16 , wherein the liner is projected at a flyer velocity from 50% higher to 140% higher than a flyer velocity produced by regular detonation. 18. A method of impacting or penetrating a target, comprising: positioning the device of claim 6 adjacent to the target at a distance up to 100 charge diameters from the target; and detonating the device. 19. The method of claim 18 , wherein the target is a demolition target, an unexploded ordnance target, a hard target, or a well and wherein the method produces a 50% or higher increase in penetration depth and 100% or higher increase in hole volume as compared to the same energetic material in the same configuration under normal detonation conditions against the same target.
