ABSTRACT: Fluorine 18 is a short lived positron emitter that is commonly used in Positron Emission Tomography (PET) for the diagnosis of cancer and Alzheimers disease. The Fluorine 18 isotope is routinely produced using an accelerator (cyclotron) via the 18O(p,n)18F reaction where the oxygen bearing medium can be either H218O gaseous 18O2. A byproduct of the reaction is the large amount of thermal power deposited in the target. Since the production rate of 18F and the heat deposited in the target are both proportional to the beam current, the production rate of 18F is limited by the targets thermal performance. This talk focuses on our efforts to design and optimize water targets for the clinical production of 18F. All students and faculty are invited to attend. UTNE Graduate Students who hold Assistantships or Fellowships are required to attend in person Refreshments will be provided in 219 Pasqua immediately following the colloquium.
