A recently filed patent (Publication Number: US20230290532A1) describes a system for the production of radioisotopes. The system includes an electron accelerator that generates an electron beam, a scanner that deviates the electron beam along a predefined scanning pattern, and a focuser that focuses the scanned beam towards a first focusing point. A converter, located between the focuser and the first focusing point, converts the focused beam into a photon beam. The converter is curved and cooled to ensure efficient conversion of the beam. The system also includes a target holder for holding a target.

The patent claims also describe variations of the system. In one variation, the scanner deviates the electron beam along two transverse axes, and the focuser focuses the scanned beam towards a second focusing point. The converter in this variation is in the shape of an ovoid cap. In another variation, the scanner deviates the electron beam along only one transverse axis, and the converter is in the shape of a section of a cylinder.

The patent claims also specify various parameters of the system. The focuser is configured to form a focused beam with a specific focusing half-angle. The bremsstrahlung converters have curved cross-sections in the irradiation planes, and their thickness is limited. The patent also mentions the use of gas or liquid forced cooling for the converter. The bremsstrahlung converters can be made of tantalum, tungsten, or titanium.

The patent claims also include a process for producing a radioisotope using the described system. The process involves loading a target onto the target holder, scanning and focusing an accelerated electron beam onto the converter to produce X-rays, and irradiating the target with the produced X-rays. The patent mentions specific targets for producing different radioisotopes.

Overall, the patent describes a system and process for the production of radioisotopes using an electron accelerator, scanner, focuser, and converter. The system offers variations in terms of scanning patterns, converter shapes, and other parameters. The process allows for the production of various radioisotopes by irradiating specific targets.
