Abstract

The study of dynamic aperture in Fermilab Recycler Ring with the latest designed low beta straight section was done by MAD. The calculation shows that the optical design of the low beta section improves the optical properties of the ring. Without misalignments, tracking calculations for on-energy particles over 10⁵ turns including all the field errors predict a dynamic aperture of 16.5σ, which is 1.6 times larger than the aperture in Recycler Ring with high beta straight section. Special attention was paid to treat gridiant magnets and their field errors in MAD and the detailed analysis was made in this paper
