A compact cyclotron accelerating H ion for producing a radioactive isotope FDG (FluoroDeoxyGlucose) for PET (Positron Emission Tomography) has been designed at Sungkyunkwan University. The H ion which generated from the PIG (Panning Ion Gauge) ion source will be accelerated at the normal conducting RF cavity which uses 83.2 MHz of resonance frequency and extracted at the carbon foil striper at the energy of 9 MeV. This cyclotron has to be small to install local hospital while FDG production needs more than 9 MeV of proton beam energy. Chasing two hare at once, deep valley type of magnet has been selected for high energy and compact cyclotron. Due to the small size of valley space where RF cavities will be installed, lots of difficulties have been introduced. Despite of those difficulties at the designing process, we could achieve resonance frequency of 83.2 MHz and Q-factor of 4500 with very compact size of RF cavity.
