Examples of neutron tube ideas date as far back as the 1930s, pre-nuclear weapons era, by German scientists filing a 1938 German patent (March 1938, patent #261,156) and obtaining a United States Patent (July 1941, USP #2,251,190); examples of present state of the art are given by developments such as the Neutristor, [3] a mostly solid state ...
The first example of a leptonic event was found in December 1972 at Gargamelle by a graduate student from Aachen. By March 1973 166 hadronic events had been found, 102 events with the neutrino beam and 64 events with the antineutrino beam. [9] However, the question of neutron background hung over the interpretation of the hadronic events.
CryoEDM is a particle physics experiment aiming to measure the electric dipole moment (EDM) of the neutron to a precision of ~10 −28 ecm. [1] The name is an abbreviation of cryogenic neutron EDM experiment. The previous name nEDM is also sometimes used, but should be avoided where there may be ambiguity.
A neutristor is a compact neutron generator made using solid-state electronics, invented at Sandia National Laboratories. [ 1 ] [ 2 ] [ 3 ] Its primary purpose is to act as a light-weight, cheaper, and safer alternative to standard neutron generation devices , benefiting industries and processes such as oilfield operations, heavy mechanical ...
The ZETA device at Harwell, United Kingdom. The toroidal confinement tube is roughly centred. The larger device on the right encircling the tube is the magnet used to induce the pinch current. ZETA, short for Zero Energy Thermonuclear Assembly, was a major experiment in the early history of fusion power research.
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 ...

The first experiments used beams of positives and negatives as fuel, and demonstrated energy capture at a peak efficiency of 65 percent and a minimum efficiency of 50 percent. [7] [8] The following experiments involved a true plasma direct converter that was tested on the Tandem Mirror Experiment (TMX), an operating magnetic mirror fusion
