Ion trajectory evaluation on CYCLONE 30

The Cyclotron is a compact device created with the purpose of accelerating positive or negative ions of H, D or α particles with energy up to 2-5% relativistic mass, whose beam is extracted and conveyed toward to the specific targets. On these accelerators, powerful electromagnetic magnets keep the particles moving in a circular trajectory. A radio frequency source provides electric fields between electrode's cavity whose polarity switches in synchronization with the passage of the pulsed particle beam. The particle kinetic energy increases at every turn. The Cyclone 30, from Ion Beam Applications, Belgium, is a negative ion accelerator, specifically for the production of radioisotopes. This device can generate beams of protons with energies up to 30 MeV and current up to 350 μA. The major goal of this study is to build a cyclone-30 model and simulate particle trajectory through the CST particle studio (2011) electromagnetic code. The pathway of a positive ion beam along its EMF (simulated on the Cyclone-type cyclotron-30 model) is presented. Herein, only the ion pathways on the main components, involving the circular path of the particle beam, were simulated. The results show the electrical field and pathway of the ion beam on the RF cavities. As conclusion, the modeling is in progress and simulations on the RF cavities were performed. In future, one can analyze the main physical parameter that involves ion acceleration on cyclone 30 based on simulations. Such investigation will provide possible performance comparisons and improvements in future designs. (author)
