| Outline of Final Research Achievements |
We carried out the study for the realization of multiple-energy synchrotron operation in order to save the irradiation time in particle therapy. By the beam simulation and experiment, we verified the effect of the method, which uses the extra frequency component of the transverse RF-filed, for the reduction of the uncontrollable spilled beam theoretically induced due to the change of the output beam energy. By this method, the amount of the uncontrollable spilled beam was reduced to below 10% compared to the ordinary method. In addition, we developed the stable and the reliable system for multiple-energy synchrotron operation by using the fast beam damp system and proved that it can be applied to practical use for the treatment.
