Summary

Teller-Ulam hydrogen bomb firing sequence, modified from Howard Morland, The Secret that Exploded (Random House, 1981).

A Warhead before firing; primary at top, first at top. Both components are fusion-boosted fission bombs.
B High-explosive fires in primary, compressing plutonium core into supercriticality and beginning a fission reaction.
C Fission in primary emits X-rays which channel along the inside of the casing, irradiating the polystyrene foam channel filler.
D Polystyrene foam becomes plasma, compressing secondary, and plutonium sparkplug inside the secondary begins to fission, supplying heat.
E Compressed and heated, lithium-6 deuterium fuel begins fusion reaction, neutron flux causes tamper to fission. A fireball is starting to form...

Français :

A Bombe avant explosion; étage de la fission en haut (primaire), étage de la fusion en bas (secondaire), toutes suspendues dans une mousse de polystyrène.
B L'explosif haute puissance détonne dans le primaire, comprimant le cœur du plutonium en mode supercritique et démarrant une réaction de fission.
C Le primaire émet des rayons X qui sont réfléchis à l'intérieur de l'enveloppe et irradient la surface du tampon (la mousse de polystyrène est transparente aux rayons X et ne sert que de support).
D Les rayons X vaporisent la surface du tampon, comprimant le secondaire, et le deutheride de lithium-6 entame une réaction de fusion.

E Comprimé et chauffé, le deutheride de lithium-6 entame une réaction de fusion, un flux de neutrons allume la fusion du tampon. Une boule de feu commence à se former...
Deutsch:

A Bombe vor der Zündung; oben die primäre Fissionsbombe; unten die sekundäre Fusionsladung; beides eingebettet in Polystyrolschaum.
B Der konventionelle Sprengstoff komprimiert den Plutoniumkern zu einer überkritischen Masse und leitet so eine Kernspaltungsreaktion ein.
C Die Fissionsbombe emittiert Röntgenstrahlung, die an der Innenseite des Gehäuses reflektiert wird. Dadurch wird das Polystyrol thermalisiert.
D Der Polystyrolschaum wird in Plasma verwandelt und komprimiert die Fusionsstufe. Der Plutoniumstab fissioniert.

E Durch die Kompression und Erhitzung beginnt das Lithium-6-deuterid zu fusionieren. Die Neutronenstrahlung spaltet das U-238 in der 2. Stufe. Ein Feuerball beginnt sich zu bilden.
Português:

A A ogiva anterior à detonação; primeiro estágio na parte superior, segundo estágio na parte de baixo. Ambos os componentes são bombas de fissão nuclear incrementadas por processos de fusão nuclear.
B Explosivos de precisão detonam o primeiro estágio comprimindo o núcleo de plutônio até a supercriticalidade, iniciando assim a reação de fissão.
C A fissão do primeiro estágio emite raios X que são canalizados pelo interior do dispositivo e irradiam a espuma de poliestireno.
D A espuma de poliestireno se transforma em plasma, comprime o segundo estágio e leva o plutônio no interior deste ("sparkplug") a fissionar aquecendo o já comprimido segundo estágio.

E O deutereto de lítio do segundo estágio, sobre alta pressão e temperatura, começa a entrar em fusão emitindo um fluxo maciço de neutrons e provocando a fissão do próprio invólucro. A explosão está começando a acontecer...
