The Strong Focusing Cyclotron development at Texas A&M University has evolved from stacks of cyclotrons to a single layer high brightness, low emittance device to produce greater than 10 mA of proton beam to a desired target at 800 MeV. The latest design has a major geometric design optimization of strong focusing quadrupoles and a modified algorithm of high gradient cavities. These optimizations address the turn separation and interaction of radially neighbouring bunches and produced a reduced the number of turns necessary to reach the desired final energy under control conditions. In this paper, we present the new design, the physics of nonlinear synchrobetratron coupling, m?h+n?v=p causing beam blow-up in other form of cyclotrons and how this work has resolved it. The cavity beam loading, and space charge effects of multi turns at low energies to reduce losses, are discussed.
