Yuri Romanov (physicist)
Yuri Aleksandrovich Romanov (; 17 June 1926 – 1 November 2010) was a Russian physicist who spent his career in the former Soviet program of nuclear weapons. Biography He was born in Moscow into a family with a strong engineering background. He went to school No.64 in Moscow in 1933. In 1941, he was evacuated to the Ural Mountains with his mother and sister. He passed the external examinations for 10th grade in 1942 and began a correspondence course of the Moscow State University in Sverdlovsk Oblast. On his return to Moscow in 1943, he joined the motor faculty of the Moscow Aviation Institute, while continuing his University studies. He moved to the engineering and physical faulty of the Moscow Mechanical Institute of Munitions as a third-year student. In 1947, he graduated with honours from his Moscow State University course. The following year he entered postgraduate study under Igor Tamm. On 10 June 1948, Tamm headed a new group of theorists which included Andrei Sakha ...

Hero Of Socialist Labour
The Hero of Socialist Labour (russian: links=no, Герой Социалистического Труда, Geroy Sotsialisticheskogo Truda) was an honorific title in the Soviet Union and other Warsaw Pact countries from 1938 to 1991. It represented the highest degree of distinction in the USSR and was awarded for exceptional achievements in Soviet industry and culture. It provided a similar status to the title of Hero of the Soviet Union, which was awarded for heroic deeds, but differed in that it was not awarded to foreign citizens. History The Title "Hero of Socialist Labour" was introduced by decree of the Presidium of the Supreme Soviet of the Soviet Union on December 27, 1938. Originally, Heroes of Socialist Labour were awarded the highest decoration of the Soviet Union, the Order of Lenin, and a diploma from the Presidium of the Supreme Soviet of the Soviet Union. In order to distinguish the Heroes of Socialist Labour from other Order of Lenin recipients, the " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inertial Confinement Fusion
Inertial confinement fusion (ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with thermonuclear fuel. In modern machines, the targets are small spherical pellets about the size of a pinhead typically containing a mixture of about 10 milligrams of deuterium 2H and tritium 3H. To compress and heat the fuel, energy is deposited in the outer layer of the target using high-energy beams of photons, electrons or ions, although almost all ICF devices used lasers. The beams heat the outer layer, which explodes outward. This produces a reaction force against the remainder of the target, which accelerates it inwards and compresses the fuel. This process also creates shock waves that travel inward through the target. Sufficiently powerful shock waves can compress and heat the fuel at the center such that fusion occurs. ICF is one of two major branches of fusion energy research, the other is magnetic confinement fusion. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinor
In geometry and physics, spinors are elements of a complex vector space that can be associated with Euclidean space. Like geometric vectors and more general tensors, spinors transform linearly when the Euclidean space is subjected to a slight ( infinitesimal) rotation. Unlike vectors and tensors, a spinor transforms to its negative when the space is continuously rotated through a complete turn from 0° to 360° (see picture). This property characterizes spinors: spinors can be viewed as the "square roots" of vectors (although this is inaccurate and may be misleading; they are better viewed as "square roots" of sections of vector bundles – in the case of the exterior algebra bundle of the cotangent bundle, they thus become "square roots" of differential forms). It is also possible to associate a substantially similar notion of spinor to Minkowski space, in which case the Lorentz transformations of special relativity play the role of rotations. Spinors were introduced in ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrophysical Plasma
Astrophysical plasma is plasma outside of the Solar System. It is studied as part of astrophysics and is commonly observed in space. The accepted view of scientists is that much of the baryonic matter in the universe exists in this state. When matter becomes sufficiently hot and energetic, it becomes ionized and forms a plasma. This process breaks matter into its constituent particles which includes negatively-charged electrons and positively-charged ions. These electrically-charged particles are susceptible to influences by local electromagnetic fields. This includes strong fields generated by stars, and weak fields which exist in star forming regions, in interstellar space, and in intergalactic space. Similarly, electric fields are observed in some stellar astrophysical phenomena, but they are inconsequential in very low-density gaseous mediums. Astrophysical plasma is often differentiated from space plasma, which typically refers to the plasma of the Sun, the solar ...

RDS-37
RDS-37 was the Soviet Union's first two-stage hydrogen bomb, first tested on 22 November 1955. The weapon had a nominal yield of approximately 3 megatons. It was scaled down to 1.6 megatons for the live test. Leading to the RDS-37 The RDS-37 was a reaction to the efforts of the United States. Previously, the Soviet Union allegedly used many of their spies in the U.S. to help them generate methods and ideas for the nuclear bomb. The creation of the hydrogen bomb required less usage of this method, although they still received help from some spies, most importantly, Klaus Fuchs. In 1945, the Soviet Union reached a decision to work on a design for a "super bomb". Also in 1945, Enrico Fermi gave lectures at Los Alamos discussing the fusion process. At the end of his lecture he stated "so far all schemes for the initiation of the super rerather vague". In the spring of 1946, Edward Teller set up a conference to assess all the information known about the hydrogen bomb. Klaus Fu ...

USSR State Prize
The USSR State Prize (russian: links=no, Государственная премия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on 9 September 1966. After the dissolution of the Soviet Union, the prize was followed up by the State Prize of the Russian Federation. The State Stalin Prize ( Государственная Сталинская премия, ''Gosudarstvennaya Stalinskaya premiya''), usually called the Stalin Prize, existed from 1941 to 1954, although some sources give a termination date of 1952. It essentially played the same role; therefore upon the establishment of the USSR State Prize, the diplomas and badges of the recipients of Stalin Prize were changed to that of USSR State Prize. In 1944 and 1945, the last two years of the Second World War, the award ceremonies for the Stalin Prize were not held. Instead, in 1946 the ceremony was held twice: in January for the works created in 1943–1944 and in June for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RDS-6s
Joe 4 was an American nickname for the first Soviet test of a thermonuclear weapon on August 12, 1953, that detonated with a force equivalent to 400 kilotons of TNT. The proper Soviet terminology for the warhead was RDS-6s, , . RDS-6 utilized a scheme in which fission and fusion fuel (lithium-6 deuteride) were " layered", a design known as the ''Sloika'' (russian: Слойка, links=no, named after a type of layered puff pastry) model in the Soviet Union. A ten-fold increase in explosive power was achieved by a combination of fusion and fission. A similar design was earlier theorized by Edward Teller, but never tested in the U.S., as the "Alarm Clock". Description The Soviet Union started studies of advanced nuclear bombs and a hydrogen bomb, code named RDS-6, in June 1948. The studies would be done by KB-11 (usually referred to as Arzamas-16, the name of the town) and FIAN. The first hydrogen bomb design was the Truba (russian: Труба, pipe/cylinder) (RDS-6t)). In M ...
