Abstract.  Novel methods of controlling the plasma boundary in tokamaks are presented, which have strong potential to substantially improve plasma performance and alleviate technological demands in next-step devices. Two categories are considered: (1) novel boundary conditions for the particle exhaust from the plasma separatrix, and (2) novel electromagnetic boundary conditions for external MHD modes. The impact of these on global plasma performance is analyzed, and substantial improvements are found.
