  • Patent number: 10595392
    Abstract: Target assembly includes a target body having a production chamber and a beam passage. The target body includes first and second grid sections that are disposed in the beam passage. Each of the first and second grid sections has front and back sides. The back side of the first grid section and the front side of the second grid section abut each other with an interface therebetween. The back side of the second grid section faces the production chamber. The target assembly also includes a foil positioned between the first and second grid sections. Each of the first and second grid sections has interior walls that define grid channels through the first and second grid sections. The particle beam is configured to pass through the grid channels toward the production chamber. The interior walls of the first and second grid sections engage opposite sides of the foil.

  • Patent number: 10354771
    Abstract: Target assembly for an isotope production system. The target assembly includes a target body having a production chamber and a beam cavity that is adjacent to the production chamber. The production chamber is configured to hold a target material. The beam cavity opens to an exterior of the target body and is configured to receive a particle beam that is incident on the production chamber. The target assembly also includes a target sheet positioned to separate the beam cavity and the production chamber. The target sheet has a side that is exposed to the production chamber such that the target sheet is in contact with the target material during isotope production. The target sheet includes graphene.

  • Patent number: 10340051
    Abstract: Radioisotope production system includes an electrical field system and a magnetic field system that are configured to direct a particle beam of charged particles along a beam path within an acceleration chamber. The magnetic field system is energized by a drive current to generate a magnetic flux into the acceleration chamber for controlling the particle beam. The radioisotope production system also includes a target system configured to hold a target material and receive the particle beam. The radioisotope production system also includes a monitoring system that is configured to: (a) determine an operating parameter of the radioisotope production system as the particle beam is directed toward the target material and (b) change the drive current, thereby changing the magnetic flux, based on the operating parameter.

  • Publication number: 20180322972
    Abstract: System includes a target assembly having a production chamber. The target assembly includes an electrode and a conductive base exposed to the production chamber. The target assembly has fluidic ports that provide access to the production chamber. The system also includes a fluidic-control system having a storage vessel and fluidic lines that connect to the fluidic ports. The storage vessel and the production chamber are in flow communication through at least one of the fluidic lines. The system also includes a power source that is configured to be electrically connected to the electrode and the conductive base. The production chamber, the electrode, and the conductive base form an electrolytic cell when an electrolytic solution is disposed in the production chamber. The power source is configured to apply voltage to the electrode and the conductive base to deposit a solid target along conductive base.

  • Patent number: 9894747
    Abstract: Radio-frequency (RF) electrode for a cyclotron. The RF electrode includes a hollowed dee having first and second surfaces that oppose each other and define a gap therebetween. The hollowed dee is configured to be electrically controlled to direct a beam of charged particles through the gap and along an orbit plane of the cyclotron. The orbit plane extends parallel to the first and second surfaces through the gap. The RF electrode also includes a bridge structure that is coupled to and extends away from the hollowed dee. The bridge structure includes a side wall that defines an interior cavity of the bridge structure. The side wall has a particle opening therethrough that coincides with or is proximate to the orbit plane such that the particle opening receives neutral particles from an orbit of the charged particles.
