    Abstract: In order to improve flux and quality of the neutron source, an aspect of the present disclosure provides a beam shaping assembly for neutron capture therapy comprising: a beam inlet; a target, wherein the target has nuclear reaction with an incident proton beam from the beam inlet to produce neutrons, and wherein the neutrons form a neutron beam defining a main axis; a moderator adjoining to the target, wherein the neutrons are moderated by the moderator to epithermal neutron energies, and wherein an outer surface of the moderator includes at least a first tapered section; a reflector surrounding the moderator, wherein the reflector leads the neutrons deviated from the main axis back to enhance epithermal neutron beam intensity; a thermal neutron absorber adjoining to the moderator, wherein the thermal neutron absorber is used for absorbing thermal neutrons so as to avoid overdosing in superficial normal tissue during therapy; a radiation shield arranged inside the beam shaping assembly, and wherein the radiation shield is used for shielding leaking neutrons and photons so as to reduce dose of the normal tissue not exposed to irradiation; and a beam outlet.

    Abstract: A fusion reactor includes an improved ability to modulate a plasma for specific purposes. The reactor operates on the ability to change at least four separate variables in each of a plurality of lenses that are independent of the other lenses. This allows for the generation of Alfvén waves and modulation of the internal plasma dynamics, actively leading to higher states of efficiency. By combining modulation of a plasma in the form of an ion beam with a solid state metal target, an efficient fast neutron source can be produced. This can lead to industrial applications such as energy generation, nuclear clean-up, the production of rare earth metals out of semi-rare ones, and helium production.

    Abstract: A first system for producing a high flux of neutrons for non-destructive testing includes a dense plasma focus device neutronically coupled to a subcritical or sub-prompt critical fission assembly. The dense plasma focus device is a source of initiating neutrons for the fission assembly, and the fission assembly is configured to multiply a number of the initiating neutrons via inducing fission. A second system for producing a high flux of neutrons includes a gas-target neutron generator neutronically coupled to a subcritical or sub-prompt critical fission assembly. The gas-target neutron generator is a source of initiating neutrons for the fission assembly, and the fission assembly is configured to multiply a number of the initiating neutrons via inducing fission.

    Abstract: A well logging tool includes a neutron generator to generate and emit energetic neutrons using substantially exclusively a T-T fusion reaction. The well logging tool can include measuring instrumentation for measurement and logging of formation parameters based on elastic scattering in subsurface formations of neutrons emitted by the neutron generator. The neutron generator can have a concentric layout, in which a cylindrical target structure loaded with tritium particles is located co-axially in an elongate cylindrical housing, with mobile tritium ions being accelerated radially inwardly into impact with the target structure. Production of the mobile tritium ions may be by field ionization through operation of a nano-structure field ionization array.
