Meson Bomb
The meson bomb was a proposed nuclear weapon that would derive its destructive force from meson interactions with fissionable material like uranium. The idea behind the bomb was rejected by most scientists, but during the Cold War, American intelligence managed to trick the Soviet Union into conducting research on this topic, which resulted in several years of wasted labor by one of the Soviet nuclear weapon research bureaus. Origins Mesons (hadronic subatomic particles composed of one quark and one antiquark, bound together by the strong interaction) were proposed to form a nuclear weapon as early as the 1940s. Early speculation suggested that the resulting bomb would be the most powerful nuclear weapon yet to have been developed. American physicist Ernest Lawrence used the potential military applications of mesons to obtain funding for its synchrocyclotron built between 1940 and 1946 at the University of California, Berkeley. Soon, however, the scientific consensus was that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been dep ...

Synchrocyclotron
A synchrocyclotron is a special type of cyclotron, patented by Edwin McMillan in 1952, in which the frequency of the driving RF electric field is varied to compensate for relativistic effects as the particles' velocity begins to approach the speed of light. This is in contrast to the classical cyclotron, where this frequency is constant. There are two major differences between the synchrocyclotron and the classical cyclotron. In the synchrocyclotron, only one ''dee'' (hollow "D"-shaped sheet metal electrode) retains its classical shape, while the other pole is open (see patent sketch). Furthermore, the frequency of oscillating electric field in a synchrocyclotron is decreasing continuously instead of kept constant so as to maintain cyclotron resonance for relativistic velocities. One terminal of the oscillating electric potential varying periodically is applied to the dee and the other terminal is on ground potential. The protons or deuterons to be accelerated are made to move ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesons
In particle physics, a meson ( or ) is a type of hadronic subatomic particle composed of an equal number of quarks and antiquarks, usually one of each, bound together by the strong interaction. Because mesons are composed of quark subparticles, they have a meaningful physical size, a diameter of roughly one femtometre (10 m), which is about 0.6 times the size of a proton or neutron. All mesons are unstable, with the longest-lived lasting for only a few hundredths of a microsecond. Heavier mesons decay to lighter mesons and ultimately to stable electrons, neutrinos and photons. Outside the nucleus, mesons appear in nature only as short-lived products of very high-energy collisions between particles made of quarks, such as cosmic rays (high-energy protons and neutrons) and baryonic matter. Mesons are routinely produced artificially in cyclotrons or other particle accelerators in the collisions of protons, antiprotons, or other particles. Higher-energy (more massive) ...

Nuclear Weapons Program Of The United States
The United States was the first country to manufacture nuclear weapons and is the only country to have used them in combat, with the bombings of Hiroshima and Nagasaki in World War II. Before and during the Cold War, it conducted 1,054 nuclear tests, and tested many long-range nuclear weapons delivery systems. Between 1940 and 1996, the U.S. Federal Government spent at least US$ in present-day terms on nuclear weapons, including platforms development (aircraft, rockets and facilities), command and control, maintenance, waste management and administrative costs. It is estimated that the United States produced more than 70,000 nuclear warheads since 1945, more than all other nuclear weapon states combined. Until November 1962, the vast majority of U.S. nuclear tests were above ground. After the acceptance of the Partial Nuclear Test Ban Treaty, all testing was relegated underground, in order to prevent the dispersion of nuclear fallout. By 1998, at least US$759 mill ...

Red Mercury
Red mercury is purportedly a substance of uncertain composition used in the creation of nuclear weapons, as well as other weapons systems. Because of the great secrecy surrounding the development and manufacturing of nuclear weapons, there is no proof that red mercury exists. However, all samples of alleged "red mercury" analyzed in the public literature have proven to be well-known, common red substances of no interest to weapons makers. Red mercury is therefore considered a hoax, perpetrated by con artists who sought to take advantage of gullible buyers on the black market for arms. There have been reports of "red mercury" on the international black markets since 1979, but the hoax seems to have been most common in the early 1990s, with very high asking prices. History References to red mercury first appeared in major Soviet and western media sources in the late 1980s. The articles were never specific as to what exactly red mercury was, but nevertheless claimed it was of gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disinformation
Disinformation is false information deliberately spread to deceive people. It is sometimes confused with misinformation, which is false information but is not deliberate. The English word ''disinformation'' comes from the application of the Latin prefix ''dis-'' to ''information'' making the meaning "reversal or removal of information". The rarely used word had appeared with this usage in print at least as far back as 1887. Some consider it a loan translation of the Russian ''dezinformatsiya'', derived from the title of a KGB black propaganda department. Defector Ion Mihai Pacepa claimed Joseph Stalin coined the term, giving it a French-sounding name to claim it had a Western origin. Russian use began with a "special disinformation office" in 1923. Disinformation was defined in ''Great Soviet Encyclopedia'' (1952) as "false information with the intention to deceive public opinion". Operation INFEKTION was a Soviet disinformation campaign to influence opinion that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Atomic Bomb Project
The Soviet atomic bomb project was the Classified information in Russia, classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Although the Soviet scientific community discussed the possibility of an atomic bomb throughout the 1930s, going as far as making a concrete proposal to develop such a weapon in 1940, the full-scale program was not initiated and prioritized until Operation Barbarossa. Because of the conspicuous silence of the scientific publications on the subject of nuclear fission by Germany, German, United States, American, and United Kingdom, British scientists, Russian physicist Georgy Flyorov suspected that the Allies of World War II, Allied powers had secretly been developing a "Weapon of mass destruction, superweapon" since 1939. Flyorov wrote a letter to Stalin urging him to start this program in 1942. Initial efforts were slowed due to the Operation Barbaro ...
