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 ...
In the middle of the 1960s direct energy conversion was proposed as a method for capturing the energy from the exhaust gas in a fusion reactor. This would generate a direct current of electricity. Richard F. Post at the Lawrence Livermore National Laboratory was an early proponent of the idea. [1]
Heavy ion therapy (e.g. carbon ions) makes use of the similarly high LET of 12 C 6+ ions. [5] [6] Because of the high LET, the relative radiation damage (relative biological effect or RBE) of fast neutrons is 4 times that of X-rays, [7] [8] meaning 1 rad of fast neutrons is equal to 4 rads of X-rays. The RBE of neutrons is also energy dependent ...
Each year, the facility hosts hundreds of researchers from universities, national laboratories, and industry, who conduct basic and applied research and technology development using neutrons. SNS is part of Oak Ridge National Laboratory , which is managed by UT-Battelle for the United States Department of Energy (DOE).
Photon-intermediate direct energy conversion (PIDEC) is a scheme for direct conversion of nuclear power to electricity. PIDEC process is somewhat similar [citation needed] to a concept of fluorescent light - as in the CFL, in the nuclear reactor the original type of energy generated is not useful to humans. CFL uses a fluorescent coating on the ...
A fast neutron is a free neutron with a kinetic energy level close to 1 M eV (100 T J/kg), hence a speed of 14,000 km/s or higher. They are named fast neutrons to distinguish them from lower-energy thermal neutrons, and high-energy neutrons produced in cosmic showers or accelerators. Fast neutrons are produced by nuclear processes:
This high-intensity superconducting linear particle accelerator for light ions, belongs to a new generation of particle accelerators. [5] The high ion current generates a copious amount of fast neutrons and light radioactive nuclei. The SARAF Phase-I accelerator was built by ACCEL Instruments (now RI Research Instruments GmbH). The novel ...
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 ...
