Basic Construction of the Teller-Ulam Device

Stage 1 High-explosive fires in primary, compressing plutonium core into supercriticality and beginning a fission reaction.

Stage 2 Fission primary emits X-rays which reflects along the inside of the casing, irradiating the polystyrene foam.

Stage 3 Polystyrene foam becomes plasma, compressing secondary, and plutonium sparkplug begins to fission.

Stage 4 Compressed and heated, lithium-6 deutheride fuel begins fusion reaction, neutron flux causes tamper to fission. A fireball is starting to form...
