Neutron generating target for neutron beam systems
Embodiments that are directed to a target for producing a high epithermal neutron yield for boron-neutron capture therapy (BNCT) treatments are disclosed. The target includes a thin flat film of solid lithium mounted onto a heat-removal support structure that is cooled with a liquid coolant and configured to maintain the turbulent flow regime for a liquid coolant and distribute the flow of coolant directed at the center of the support structure toward a periphery of the support structure via a plurality of channels formed in the support structure. The support structure includes a nozzle located at its center to direct coolant flow outwardly from the center to avoid stagnant water flow at the center of the support structure. Systems, device, and methods utilizing the approaches are also described.

APPARATUS FOR PREPARING MEDICAL RADIOISOTOPES
Apparatus for radioisotope production includes housing, a plurality of target disks inside the housing and a curved windows positioned convex inward toward the disks. During operation, coolant flows though the housing across the disks and windows while electron beams passes through the window and the disks. The window temperature increases, rising the fastest in the middle of the window where the electron beam hits the window. A flat window would buckle because the center would deform during thermal expansion against the relatively unaffected periphery, but the curved window shape allows the window to endure high thermal and mechanical stress created by a combination of heating from the electron beam(s) and elevated pressure from coolant on the inside of the window. Such a window may be used for applications in which a pressurized coolant acts on only one side of the window.

FLEXIBLE IRRADIATION FACILITY
An irradiation facility for a nuclear reactor, a method of removing thermal heat from an irradiated object and adjusting an energy distribution/neutron/gamma-ray flux ratio of irradiation, and a product obtainable by the method.
BELT-SHAPED NEUTRON SOURCE
A continuous, thin layer of neutron source material, for example solid lithium, is formed into a belt. The belt is continuously advanced in front of a proton source to generate neutrons from the lithium target. Additionally, the belt is continuously cooled, as it passes through a gas cooling section. Through the continuous motion and cooling of the lithium target, the belt can provide an effective neutron source without melting the target neutron source material.
Targets and methods for target preparation for radionuclide production
The invention relates to nuclear technology, and to irradiation targets and their preparation. One embodiment of the present invention includes a method for preparation of a target containing intermetallic composition of antimony Ti—Sb, Al—Sb, Cu—Sb, or Ni—Sb in order to produce radionuclides (e.g., tin—117m) with a beam of accelerated particles. The intermetallic compounds of antimony can be welded by means of diffusion welding to a copper backing cooled during irradiation on the beam of accelerated particles. Another target can be encapsulated into a shell made of metallic niobium, stainless steel, nickel or titanium cooled outside by water during irradiation. Titanium shell can be plated outside by nickel to avoid interaction with the cooling water.
