The Hydrogen bomb or H-bomb is a nuclear fusion weapon which is also broadly referred as thermonuclear weapons. This is one of the most powerful destructive weapons invented by Dr. Edward Teller in 1952. This project of working and creating a nuclear weapon was jointly performed by Teller and another scientist Stanislaw Ulam, whose creation – the Hydrogen bomb – was successfully made and detonated to produce an explosion almost 500 times more powerful than the traditional Atomic bomb.
By 1954, the United States had successfully detonated two H-bombs which produced a force close to 15 megatons which was doubly powerful. Further research on the hydrogen bomb was done to primarily reduce its size and make it possible to transport it through vehicles. The Soviet Union however had created a hydrogen bomb much earlier than 1952 but its design was not very efficient and hence could not result in the power that they intended to induce. Hence history lends credit to Teller and Ulam for their breakthrough working principle.
Contrary to atomic bombs which work on the principle of nuclear fission, thermonuclear weapons work on the principle of fusion. According to the Teller-Ulam design, the different parts of the weapon are grouped into stages in which each stage provides the heat and energy required to initiate the next process. A fission bomb is placed in a container having a fusion fuel within it, like deuterium or tritium.
The Hydrogen bomb is therefore more powerful in intensity as it uses the same process to produce energy as the Sun – the fusion process.
