 particle interactions with each other and with stationary and time-dependent fields make motion in accelerators quite complex and, in general, non-integrable.&nbsp; As a consequence, nearly all accelerators are limited in their performance by an on-set of chaotic
 particle behavior, instabilities and associated uncontrolled beam losses.&nbsp; Improved integrability in both electron and ion accelerators has been a long-sought-after goal of accelerator physicists.&nbsp; Recently, we have proposed several examples of integrable
 nonlinear accelerator focusing systems. &nbsp;</span><span style="color:black"><o:p></o:p></span></p>
