Radiohalogen targetry at University of Wisconsin

Over the last two years, University of Wisconsin has developed new target systems for the production of fluorine-18, bromine-76 and iodine-124. These new systems include the successful replacement of a double-foiled silver water target for the production of [18F]-F- with a niobium body, isolated from the cyclotron vacuum by a single grid supported entrance foil. This manuscript highlights the success of our 18F-fluoride target over its two years of maintenance free operation. A new solid target system for the production of long-lived halogens, with specific reference to iodine-124, is also introduced
