According to researcher Chuck Hansen, the W34 Python was a gas-boosted fission primary used in several designs of American thermonuclear weapons.. Hansen's research indicates that the W34 Python primary was used in the US B28 nuclear bomb, W28, W40, and W49, and as a boosted fission warhead without a thermonuclear second stage in several other weapons.
An activation product is a material that has been made radioactive by the process of neutron activation.. Fission products and actinides produced by neutron absorption of nuclear fuel itself are normally referred to by those specific names, and activation product reserved for products of neutron capture by other materials, such as structural components of the nuclear reactor or nuclear bomb ...
Neutron generators are neutron source devices which contain compact linear particle accelerators and that produce neutrons by fusing isotopes of hydrogen together. The fusion reactions take place in these devices by accelerating either deuterium , tritium , or a mixture of these two isotopes into a metal hydride target which also contains ...
Some isotopes undergo spontaneous fission (SF) with emission of neutrons.The most common spontaneous fission source is the isotope californium-252. 252 Cf and all other SF neutron sources are made by irradiating uranium or a transuranic element in a nuclear reactor, where neutrons are absorbed in the starting material and its subsequent reaction products, transmuting the starting material into ...
Phoenix, formerly known as Phoenix Nuclear Labs, is a company specializing in neutron generator technology located in Monona, Wisconsin, United States.Founded in 2005, the company develops nuclear and particle accelerator technologies for application in medicine, defense and energy.
Red: uranium-238, light green: plutonium-239, black: fission products. Intensity of blue color between the tiles indicates neutron density A traveling-wave reactor ( TWR ) is a proposed type of nuclear fission reactor that can convert fertile material into usable fuel through nuclear transmutation , in tandem with the burnup of fissile material.
The Soreq Applied Research Accelerator Facility (SARAF) is a superconducting radiofrequency linear accelerator and neutron source, located at the Soreq Nuclear Research Center in Yavne, Israel. Its highly configurable neutron spectrum and produced range of light radionuclides makes it suitable for a range of research topics that previously ...
The release of neutrons from the nucleus requires exceeding the binding energy of the neutron, which is typically 7-9 MeV for most isotopes. Neutron sources generate free neutrons by a variety of nuclear reactions, including nuclear fission and nuclear fusion. Whatever the source of neutrons, they are released with energies of several MeV.
