Targets for the CC-18/9 cyclotron Olof Solin,
Stefan Johansson, Esa Kokkomäki, Tom
Wickström, Simo Vauhkala and Jörgen
Bergman Turku PET Centre, Accelerator Laboratory

• Main characteristics of the CC-18/9
• 18 MeV protons, 9 MeV deuterons, fixed energy
• negative ion acceleration, gt50 mA extracted beam
• three extraction ports, one beamline
• switching magnet for 4 irradiation positions

• Main tasks of the CC-18/9
• Routine and continuous production of 11C, 13N,
  15O and 18F
• Gas and water target materials
• Occasional production of radioisotopes of e.g.
  Cu, Br, Tc, I
• Mostly solid or molten target materials

• Targets on beam lines
• Cyclotron vacuum protection in case of foil
  rupture
• Possibility to focus and spread out the beam on
  target
• Easy access to target chambers
