Description
The ultra-low emittance complex bend lattice introduces significant challenges for nonlinear beam dynamics due to its stronger focusing. Achieving high injection efficiency and long beam lifetime requires sufficiently large dynamic aperture and momentum aperture. Recent studies have shown that chaos indicators provide an effective method of suppressing nonlinear chaos and improving nonlinear beam dynamics performance. In an asymmetric complex bend lattice, due to the existence of injection cell, the chromatic sextupole families are regrouped and additional octupoles are introduced to increase the number of optimization knobs. This paper presents optimized dynamic aperture and momentum aperture obtained through chaos indicator minimization.
