It was eventually re-worked in the MK 4 Fat Man bomb, which was similar in principle but was appropriate for long-term stockpiling, use by non-experts, and used a more efficient implosion system web board (with web board a 60 point implosion system, compared to the 32 point weapon used in the war). [edit] The Gadget Schematic cross-section of the "gadget"; some boundaries are approximate. From left to right (outside inward): web board dural casing, ~140 cm inner diameter exploding-bridgewire detonator (allows for instantaneous detonation of explosives) faster explosive, Composition-B; 60% RDX, 39% TNT, 1% wax slower explosive (Baratol) faster explosive, "amplifier" aluminum–boron "pusher" (absorbs stray neutrons and widens/smooths implosion pulse) natural-uranium "tamper" (neutron reflector, inertial containment, improves efficiency, reduces the amount of fission material needed) the "pit"; plutonium-239–plutonium-240–gallium delta-phase alloy (96%–1%–3% by molality) (fissionable material); sphere with a diameter of 9 cm, with a 2.5
