The Alternating Gradient Synchrotron(AGS) consists of 12 super-periods. Each period consists of 5 FODO cells. For its regular operations, the betatron tunes are set at Qx(horizontal tune)=8.6, Qy(vertical tune)=8.7. The maximum betatron function in the AGS is about 22m. What’s the one turn transfer matrix at the location of maximum betatron function?
