3. Basics of PET Tracer Production

4. Generates high-energy particles Generate PET radionuclide Generates TRACER

13. As the beam spirals out, its frequency does not decrease, and must continue to accelerate, as it travelling more distance in the same time.

15. Max KE achievable: ………… ..

19. Ion source system (cont) Ion Source

21. Charged Particle in an EM Field

23. RF System (cont) Flaps Fine tuning RF frequency Stem Supplying RF power to Dee’s

25. DEEs Ion Source

26. Particle acceleration

29. Beam Extraction (cont) H - Ion source Creates the ion Orbits controlled by magnet field RF System Accelerates the ion Carbon foil H + Extraction System Changes polarity of ions 16.5 MeV p+ e- e- p+ e- e- p+ e- e-
