fusion boosting造句

• It is thought that the fusion boosting failed to increase the yield.
• Larger total yields and higher efficiency are possible, since the chain reaction can continue beyond the second generation after fusion boosting.
• The yield limitation was rendered irrelevant in mid-1950s with the advent of fusion boosting, and later with using of fusion weapons.
• The " Pendant " test had a yield of about 24 kilotons, and it used solid hydrogen fusion boosting using lithium deuteride.
• Although this makes the material less attractive for weapons production, it could be used in weapons at varying degrees of sophistication / with fusion boosting.
• Since implosion weapons can be designed that will achieve yields in this range even if neutrons are present at the moment of criticality, fusion boosting allows the manufacture of efficient weapons that are immune to predetonation.
• However, modern nuclear weapons use fusion boosting, which mitigates the predetonation problem; if the deuterium-tritium fusion, the resulting burst of neutrons will fission enough plutonium to ensure a yield of tens of kilotons.
• Neutron reflectors, compressing the fissile core via implosion, fusion boosting, and " tamping ", which slows the expansion of the fissioning core with inertia, allow nuclear weapon designs that use less than what would be one bare-sphere critical mass at normal density.
• The efficiency of the hollow pits can be further increased by injecting a 50 % / 50 % mixture of deuterium and tritium into the cavity immediately before the implosion, so called " fusion boosting "; this also lowers the minimum amount of plutonium for achieving a successful explosion.
• A sense of the potential contribution of fusion boosting can be gained by observing that the complete fusion of one TJ ) of energy, and would by itself result in a 29.7 % efficiency for a bomb containing 4.5 kg of plutonium ( a typical small fission trigger ).
• Carey Sublette of Nuclear Weapon Archive argues that Ulam came up with the radiation implosion compression design of thermonuclear weapons, but that on the other hand Teller has gotten little credit for being the first to propose fusion boosting in 1945, which is essential for miniaturization and reliability and is used in all of today's nuclear weapons.
• Fusion boosting is achieved by introducing tritium and deuterium gas ( solid lithium deuteride-tritide has also been used in some cases, but gas allows more flexibility and can be stored externally ) into a hollow cavity at the center of the sphere of fission fuel, or into a gap between an outer layer and a " levitated " inner core, sometime before implosion.
• :: I think when you are talking about enrichment levels below 93.5 % you are essentially asking about the difference between a nuclear weapon and a dirty bomb ( assuming you do not have other very high-level technologies I imagine that there are ways to increase the efficiency of a lesser enriched bomb if you could do things like use very reflective tampers and fusion boosting ) .-- Fastfission 00 : 31, 12 September 2006 ( UTC)
