Spherical implosion

WebThis design combines the several techniques, explosive driven flying plates, shock profiling from collisions with shock buffers, and the convergence effect of thick collapsing shells, and spherical implosion waves. In principal, a highly symmetric implosion system could produce fusion conditions in a very small central region. WebFurther miniaturization was achieved by linear implosion. An elongated subcritical solid pit, reshaped into a supercritical spherical shape by two opposite shock waves, and later a hollow pit with more precisely shaped shock waves, allowed construction of relatively very small nuclear warheads.
