BEAM OPTICS AND DYNAMICS OF FFAG ACCELERATORS

As a versatile accelerator, especially for application with high repetition and high current beams, the FFAG (Fixed Field Alternating Gradient) synchrotron attracts growing attention. We will discuss the design procedure and beam dynamics study from a modern view based on recent progress in high-energy accelerators. Comparison between brute force tracking with direct use of 3D field mapping data and a newly introduced way modeling the entire field region with a collection of thin elements is presented.
