| Outline of Final Research Achievements |
For numerical analysis of charged particle beam in accelerator, the relation between the accuracy of the motion, which corresponds to the resolution of the phase space distribution, and the degree of freedom, which corresponds to the number of particles in the charged particle beam, is important. Based on the renormalization group in the statistical mechanics, we developed a new method to analyze the relation between the resolution of the phase space and the degree of freedom for macro-particle model, which had same mass-to-charge ratio and was widely used to express the charged particle beam. Based on the new method, we developed a new numerical simulation code. Using the new code, space charge dominant beam was analyzed, and confirmed that the degree of freedom around the edge of the beam distribution affected the resolution of the phase space distribution. The results are effective to improve the resolution for the numerical analysis of the charged particle beam.
