Description

Nonlinear beam dynamics is essential for a low emittance complex bend lattice. Therefore, a multi-objective optimization to simultaneously achieve a large dynamic aperture and momentum aperture is needed, although it is becoming increasingly challenging. In this paper, we discuss the search for optimal arrangement of chromatic sextupole and octupoles as well as optimal tunes of the ring. We also present the recent results of optimized dynamic aperture and momentum aperture for a complex bend lattice.
