  2. Neutron generator - Wikipedia

    en.wikipedia.org/wiki/Neutron_generator

    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 ...

    David Charles Hahn (October 30, 1976 – September 27, 2016), sometimes called the "Radioactive Boy Scout" and the "Nuclear Boy Scout" was an American nuclear radiation enthusiast who built a homemade neutron source at the age of seventeen.

    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.

  5. Nuclear fission - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fission

    The 1 September 1939 paper by Bohr and Wheeler used this liquid drop model to quantify fission details, including the energy released, estimated the cross section for neutron-induced fission, and deduced 235 U was the major contributor to that cross section and slow-neutron fission. [42] [5]: 262, 311 [4]: 9–13

    An example of an induced nuclear fission event. A neutron is absorbed by the nucleus of a uranium-235 atom, which in turn splits into fast-moving lighter elements (fission products) and free neutrons. Though both reactors and nuclear weapons rely on nuclear chain reactions, the rate of reactions in a reactor is much slower than in a bomb.

  7. Neutron source - Wikipedia

    en.wikipedia.org/wiki/Neutron_source

    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 ...

  8. Modulated neutron initiator - Wikipedia

    en.wikipedia.org/wiki/Modulated_neutron_initiator

    A modulated neutron initiator is a neutron source capable of producing a burst of neutrons on activation. It is a crucial part of some nuclear weapons, as its role is to "kick-start" the chain reaction at the optimal moment when the configuration is prompt critical. It is also known as an internal neutron initiator.

  9. Nuclear weapon design - Wikipedia

    en.wikipedia.org/wiki/Nuclear_weapon_design

    There is another source of free neutrons that can spoil a fission explosion. All uranium and plutonium nuclei have a decay mode that results in energetic alpha particles. If the fuel mass contains impurity elements of low atomic number (Z), these charged alphas can penetrate the coulomb barrier of these impurity nuclei and undergo a reaction ...
