  This paper shows the results of the tune analysis by fitting the particle's trajectory around equilibrium orbits of KIRAMS-430 superconducting cyclotron. In the analysis, the beam trajectory fits well with sine waves of 3 frequencies of νr, NSector-νr, NSector+νr in radial motion and νz, NSector-νz, NSector-νz at axial motion. The home-made SIMCODE tracking package with Mathematica program has been used for this analysis to get equilibrium orbits and simulate beam trajectories, and analysis the tune of thos trajectories with 3 sine waves.

  An accurate beam transverse size control at the iso-center is one of the most crucial clinical requirements for particle therapy. The RMS beam transverse sizes at the iso-center are in 3 mm to 10 mm range with beam energy from 430 MeV/u to 145 MeV/u. Beam tracking study with realistic magnetic field distribution is mandatory to predict accurate beam transverse size. In order to estimate beam size accurately, the effects of chromaticity and multi-pole field components were evaluated with various beam tracking codes. With the comparisons, further analysis direction is established.
