TUPAN007 | 3-D Magnetic Calculation Methods for Spiral Scaling FFAG Magnet Design | 1401 |
|
||
Funding: ANR (French Research Agency) 2-D and 3-D magnetic calculation tools and methods have been developed at SIGMAPHI, in collaboration with IN2P3/LPSC, to design spiral FFAG magnets. These tools are currently being used for RACCAM spiral scaling FFAG magnet design. In the particular case of a spiral gap shaped magnet, a careful magnetic design has to be realized in order to keep both vertical and horizontal tunes constant during acceleration process. Promising results, obtained from tracking in 3-D field maps, demonstrate the efficiency of the horizontal and vertical tune adjustment methods presented in this paper. |

TUPAN008 | Spiral FFAG for Protontherapy | 1404 |
|
||
High rep rate of the FFAG accelerator and compactness of the spiral type of the design makes it a good candidate as medical machine for protontherapy and for biological research. The variable energy extraction with various methods is discussed. The principle of the lattice design together with the injection scheme and the beam dynamics simulations are presented. The spiral magnet design undertaken in the frame of the RACCAM project is briefly described. |
