    摘要： A Thorium molten salt energy system is disclosed that includes a proton beam source for producing a proton beam, that can vary between a first energy level and a second energy level of, where the generated proton bean can be directed into a main assembly containing both Thorium-containing molten salt and Thorium fuel rods, each containing an inner Beryllium element and an outer solid Thorium element. The generated proton beam can be shaped and directed to impinge upon Lithium within the molten salt to promote the generation of thermal neutrons and the fission of Uranium within the molten salt. The generated proton beam can also be shaped and directed to impinge upon the Beryllium within the Thorium fuel rods to promote the generation of high energy neutrons.

    摘要： The present invention discloses a compact integrated deuterium-deuterium (D-D) neutron generator. A hemispherical metal head is disposed inside a cylindrical ceramic shell of the generator and is provided therein with an ion source and an ion source power supply. An inner ceramic insulated cylinder and an outer ceramic insulated cylinder are disposed between a metal plate of the metal head and a baseplate of the generator, and an isolated power supply system and a high-voltage power supply are disposed between the inner ceramic insulated cylinder and the outer ceramic insulated cylinder. A rear end of an extraction accelerating electrode disposed inside the inner ceramic insulated cylinder protrudes from the generator and is then connected to a target holder disposed outside the baseplate. A target is disposed inside the target holder, the target is at ground potential, and a cooling water interface is disposed on the target holder.

    摘要： A continuous wave ion linear accelerator PET radioisotope system is disclosed. The system includes a high brightness H− ion source, a continuous wave RF quadrupole structure, and continuous wave RF interdigital structures to accelerate the ion beam to about 14 MeV. A high energy beam transport system is also described that includes a photo-detachment beam splitter and a magnet lattice for forming the proton beam into a beam having a Waterbag beam profile. The system also includes one or more targets upon which the proton beam is incident. The targets are either a high power metallic target oriented at about 10 degrees or a low thermal conductivity target oriented at about 35 degrees. The invention includes a method of producing PET isotopes by use of the systems described.

    摘要： The radionuclide 43Sc is produced at commercially significant yields and at specific activities and radionuclidic purities which are suitable for use in radiodiagnostic agents including imaging agents. In a method, a solid target having an isotopically enriched target layer prepared on an inert substrate is positioned in a specially configured target holder and irradiated with a charged-particle beam of protons or deuterons. The beam is generated using an accelerator such as a biomedical cyclotron at energies ranging from 3 to about 22 MeV. The method includes the use of three different nuclear reactions: a) irradiation of enriched 43Ca targets with protons to generate the radionuclide 43Scin the nuclear reaction 43Ca (p,n)43Sc, b) irradiation of enriched 42Ca targets with deuterons to generate the radionuclide 43Sc in the nuclear reaction 42Ca(d,n)43Sc, and c) irradiation of enriched 46Ti targets with protons to generate the radionuclide 43Sc in the nuclear reaction 46Ti (p,a)43Sc.

    摘要： Accelerator based systems are disclosed for the generation of isotopes, such as molybdenum-98 (“99Mo”) and metastable technetium-99 (“99mTc”) from molybdenum-98 (“98Mo”). Multilayer targets are disclosed for use in the system and other systems to generate 99mTc and 98Mo, and other isotopes. In one example a multilayer target comprises a first, inner target of 98Mo surrounded, at least in part, by a separate, second outer layer of 98Mo. In another example, a first target layer of molybdenum-100 is surrounded, at least in part, by a second target layer of 98Mo. In another example, a first inner target comprises a Bremsstrahlung target material surrounded, at least in part, by a second target layer of molybdenum-100, surrounded, at least in part, by a third target layer of 98Mo.

    摘要： A method of producing energy from condensed hydrogen clusters created from the desorption of hydrogen atoms from a primary material. The method of producing energy from condensed hydrogen clusters generally includes positioning at least a desorbing side of a primary material within a sealed reactor chamber. Mono-isotopic hydrogen atoms are absorbed by the primary material. Condensed hydrogen clusters are formed from the desorption of the hydrogen atoms from the primary material. Stability of the condensed hydrogen clusters is maintained by prevention of covalent bond formation and recombination into hydrogen molecules. A nuclear reaction and spallation of the stable condensed hydrogen clusters is initiated to produce reaction products. Energy may be harvested from the reaction products, such as through a coolant.
