Description
Magnetic design and beam optics studies have been carried out for a K100 cyclotron, which can accelerate Q/A=1/2 ions to the maximum energy of 25 MeV/u. Since proton acceleration using H2+ instead of H+ or H- can double the maximum beam current primarily limited by space charge effects at the injection energy of compact cyclotron, we expect a maximum current of over 2 mA can be achieved by existent cyclotron technology. In addition, D+, He2+ can be accelerated with slight adjustments of rf frequency so as to produce fast neutrons and medical isotopes such as 211At for advanced cancer therapy. Also, we consider employing a charge stripping method to extract H2+ at an energy of around 10 MeV to produce low-energy neutrons more optimally. I will present major features of the cyclotron design.
