Magnetic Feedback Control of Plasma Shape and Turbulence via PID LQR Hall Effect Sensors

Neoclassical and turbulent transport are significant plasma physics challenges that must be overcome to achieve sustained ignition in a magnetic thermonuclear reactor. Achieving magnetic field lines, both closed and open, that can support MHD optimized Shafranov shifts to more corralled banana orbits within a toroidal annulus will result in better fusion. Proposed is a feedback circuit that can sense plasma fields, calibrate the output of controlling coils to an H mode laminar plasma, and modify field strength to control both shape and turbulence. Fusion magnetic bottles consist of a combination of toroidal, poloidal, solenoidal, and controlling coils. A Lagrangian that has the field polynomials and a molecular dynamics simulation should provide computational models that can be implemented in a future DEMO reactor.
