| Outline of Final Research Achievements |
In order to make superconducting magnets for heavy particle beam rotating gantries extremely lightweight, we conducted design study on a superconducting dipole magnet incorporating active shielding technology. As a result, we succeeded in establishing a design method for a dipole coil with active shielding. We also clarified the effect of the electromagnetic force generated by coil energization and the thermal stress generated when cooling on the superconducting coil shape.Furthermore, we revealed the effect of the coil shape on the stray field.
