   Abstract:
   Many mod­ern light source stor­age rings use a basic mag­net­ic lat­tice struc­ture con­sist­ing of a num­ber of repet­i­tive pe­ri­od­ic lat­tice block, the super pe­ri­ods. The study of one su­per-pe­ri­od can re­veal the dy­nam­i­cal pro­pri­eties of the stor­age ring. Un­like the tra­di­tion­al ap­proach of study­ing the one-turn map of the stor­age ring, the work fo­cus­es on the study of a su­per-pe­ri­od lat­tice, which al­lows us to gain new in­sight into the stor­age ring dy­nam­ics using a sim­pler mag­net­ic struc­ture. In this paper, both an­a­lyt­i­cal and nu­mer­i­cal tech­niques, in­clud­ing Lie Al­ge­bra and Nor­mal Form, and par­ti­cle track­ing and fre­quen­cy anal­y­sis, are used to study the non­lin­ear dy­nam­ics of one su­per-pe­ri­od of a stan­dard dou­ble-bend achro­mat (DBA) and triple-bend achro­mat (TBA) with two or more non­lin­ear el­e­ments (e.g. sex­tupoles). The re­la­tion­ship be­tween the su­per-pe­ri­od dy­nam­ics and stor­age ring dy­nam­ics is ex­plored in terms of the glob­al lat­tice tun­ing and local lat­tice se­lec­tion for straight sec­tions.
