WebNeutron generator theory and operation. Small neutron generators using the deuterium (D, hydrogen-2, 2 H) tritium (T, hydrogen-3, 3 H) fusion reactions are the most common accelerator based (as opposed to radioactive isotopes) neutron sources. In these systems, neutrons are produced by creating ions of deuterium, tritium, or deuterium and tritium … WebLaser-generated proton beams. High intensity lasers create energetic protons when the laser interacts with a material. A simple acceleration mechanism, Target Normal Sheath …
