The target includes a body configured to encase a target material and having a passageway for a charged particle beam, and a component within the body, wherein the charged particle beam induces radioactivity in the component. Additionally, at least one portion of the body is formed from a material having a density value greater than a density value of aluminum to shield the component.

摘要： A cyclotron that includes a magnet yoke that has a yoke body that surrounds an acceleration chamber and a magnet assembly. The magnet assembly is configured to produce magnetic fields to direct charged particles along a desired path. The magnet assembly is located in the acceleration chamber. The magnetic fields propagate through the acceleration chamber and within the magnet yoke. A portion of the magnetic fields escape outside of the magnet yoke as stray fields. The magnet yoke is dimensioned such that the stray fields do not exceed 5 Gauss at a distance of 1 meter from an exterior boundary.

摘要： The invention relates to a method and apparatus that can improve the lifetime and performance of an ion source in a cyclotron. According to one embodiment, the invention comprises an ion source tube for sustaining a plasma discharge therein. The ion source tube comprises a slit opening along a side of the ion source tube, wherein the slit opening has a width less than 0.29 mm. The ion source tube also comprises an end opening in an end of the ion source tube. The end opening is smaller than an inner diameter of the ion source tube and is displaced by 0-1.5 mm from a central axis of the ion source tube toward the slit opening. The plasma column is displaced 0.2 to 0.5 mm relative the slit opening. The ion source tube comprises a cavity that accommodates the plasma discharge. The invention also relates to a method for making an ion source tube.

摘要： An isotope production system that includes a cyclotron having a magnet yoke that surrounds an acceleration chamber. The cyclotron is configured to direct a particle beam from the acceleration chamber through the magnet yoke. The isotope production system also includes a target system that is located proximate to the magnet yoke. The target system is configured to hold a target material and includes a radiation shield that extends between the magnet yoke and the target location. The radiation shield is sized and shaped to attenuate gamma rays emitted from the target material toward the magnet yoke. The isotope production system also includes a beam passage that extends from the acceleration chamber to the target location. The beam passage is at least partially formed by the magnet yoke and the radiation shield of the target system.
