The hydrogen bomb and controlled fusion

While in grade 7 (in 1941) upon reading "Introduction to Nuclear Physics", he showed interest in this topic. While in the military on Sakhalin Lavrentiev was educating himself, using the library of technical literature and college textbooks. With his measly military allowance he subscribed for the journal Uspekhi Fizicheskikh Nauk

. (Advances in physics science) In 1948, Lavrentiev was instructed to prepare a lecture on nuclear physics. With a few days to prepare, he had time to rethink the problem and wrote a letter to the Central Committee of the CPSU (b). From Moscow came an order to create for him an atmosphere where he could work. In a guarded room dedicated to him, he wrote his first article, which he sent in July 1950 via secret mail to the department of heavy equipment engineering of the Central Committee.

His proposal consisted of two parts. Firstly, he proposed an implementation of a hydrogen bomb, based on lithium deuteride. In the second part of his work, he describes how to obtain electricity from a controlled thermonuclear reaction
Fusion power
Fusion power is the power generated by nuclear fusion processes. In fusion reactions two light atomic nuclei fuse together to form a heavier nucleus . In doing so they release a comparatively large amount of energy arising from the binding energy due to the strong nuclear force which is manifested...

. Sakharov reviewed his work and wrote in a review the following:

. A few months later he was summoned to the Minister of the measuring instrument (the nuclear industry) V.A. Makhnev, and a few days later - to the Kremlin to the chairman of an ad hoc committee on atomic and hydrogen weapons, Lavrentiy Beria

After meeting with Beria, Lavrentiev given a room in the new house and a scholarship. He was allowed to attend lectures at will and to request on-demand delivery of scientific literature. He was assigned a math supervising professor PhD A.A. Samarskii (later - academician and Hero of Socialist Labor).

In May 1951, Lavrentiev got access to newly opened State program of fusion research. (Laboratory of instrumentation of the USSR, currently - Kurchatov Institute), where were carried out research on high temperature plasma physics classified as top-secret. There was already ongoing testing and development of Andrei Sakharov

's ideas for the fusion reactor.

On August 12, 1953 the Soviet Union tested thermonuclear warhead based on the lithium deuteride. Unlike other participants in the development of new weapons that have received state awards, ranks and awards, Lavrentiev was denied admission to the lab, and was forced to write a thesis project without access to the lab and without a scientific adviser. Nonetheless, he graduated with honors based on his theoretical work on controlled thermonuclear fusion.

In the spring of 1956 Lavrentiev was sent to Kharkiv Theoretical Physics School

Restoring primacy

" (Advances in physics science) published Lavrentiev's biography; his proposal that was mailed from Sakhalin, July 29, 1950; the review by Sakharov, and Beria's orders, which were kept in the Archives of the Russian Federation President designated as secret. That has reestablished the primacy of his scientific achievement.
