Schematic cross-section of the first atomic bomb, which was tested at the Trinity site in the framework of the Manhattan Project, and was nicknamed the gadget

• made from Nuclear Weapon Archive's description
• about 630 pixels/metre
• thickness of casing not given (It may not have been very thick. If I understand high explosive--which I don't claim to do--a casing rupture would not have mattered after a few microseconds. And notice, for instance, that half the bolts may have been left out of Gadget's one flange.[1])
• the lens based on 78:47 detonation-speed ratio ([2] pg6) and 10 cm between EBW and Baratol
• thickness of amplifier layer not given

[edit] Caption

Layers go from left-to-right:

• ██ 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 molarity)(fissionable material); sphere with a diameter of 9 cm, with a 2.5 cm cavity and a plutonium plug to allow initiator insertion; mass 6.2 kg

• ██ air gap

• ██ beryllium–polonium-210 "initiator" (the "urchin"), neutron source
