ENERGY FOCUSSING

摘要

A method of producing a localised concentration of energy comprises providing a series of projectiles (8) and firing said projectiles (8) at a target (2; 4; 6; 14; 16; 18; 20; 30; 32; 34; 36; 38; 42). An apparatus for producing localised concentration of energy comprises: means for providing a series of projectiles (8) and means for firing said projectiles (8) at a target (2; 4; 6; 14; 16; 18; 20; 30; 32; 34; 36; 38; 42). The target (2; 4; 6; 14; 16; 18; 20; 30; 32; 34; 36; 38; 42) is configured such that upon striking the target, a projectile (8) traps and compresses a volume of gas (10) between the projectile and the target. The target (2; 4; 6; 14; 16; 18; 20; 30; 32; 34; 36; 38; 42) and the projectile (8) are also configured such that impact of the projectile onto the target gives rise to a converging Shockwave (12) inside the trapped volume of gas (10).
