| 内容記述 | A study of superconducting combined function magnets with higher order<br /> harmonics has been performed, aiming at an application for the Fixed Field<br /> Alternating Gradient (FFAG) accelerator. The FFAG accelerator magnet is<br /> required to have a nonlinear magnetic field that increases with <i>k</i>-th power of<br /> the orbit radius, where <i>k</i> is the field index in the accelerator. The required<br /> nonlinear magnetic field has been investigated with combined function coils,<br /> which consist of a large elliptical aperture, designed by using a computer<br /> code that was specifically developed for this purpose. It has been under-<br />stood from tracking that the integrated magnetic field along the beam path<br /> is the important parameter to be optimized. The field quality was evaluated<br /> with a particle trajectory simulation in which a particle could circulate well<br /> with stable tune. A prototype coil has been successfully developed by using<br /> a 6-axis CNC winding machine. The magnetic field and cryogenic character-<br />istics of the prototype have been verified in warm and cold measurements.<br /> As a consequence, a superconducting combined function coil design has been<br /> made for future application in the FFAG accelerator, and its technical fea-<br />sibility has been verified with the prototype magnet development and the<br /> performance test. | |||||||
