Two-Point Detonation Linear Implosion The two ends of a cylinder, or an ovoid, could be driven toward each other to create a high-density sphere. This two-point detonation greatly reduced the diameter and the weight of the primary. A linear implosion allows for a low density, elongated non-spherical (football shaped) mass to be compressed into a supercritical configuration without using symmetric implosion designs. This assembly is accomplished by embedding an elliptical shaped mass in a cylinder of explosive. The explosive is detonated on both ends, and an inert wave shaping device is required in front of the detonation points. Extensive experimentation was needed to create a workable form, but this design enables the use of Plutonium as well as Uranium.
