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. | ||
