  • Tantalum water target body for production of radioisotopes
    Patent number: 7831009
    Abstract: An apparatus for containing and cooling enriched water for the production of activated fluorine (18F). A target assembly includes internal cooling channels in which developed flow of a coolant removes the heat from the target liquid in the target chamber. In one embodiment, the target assembly is fabricated of tantalum.

  • Tantalum water target body for production of radioisotopes
    Publication number: 20050084055
    Abstract: An apparatus for containing and cooling enriched water for the production of activated fluorine (18F). A target assembly is fabricated with internal cooling channels having minimal conduction paths and high Reynolds number flows. In one embodiment, the target assembly is fabricated of tantalum, which has superior oxidation resistance over silver. The superior oxidation resistance and increased cooling capacity allows for high beam currents.
