Abstract Text:
Research on controlled nuclear fusion has been largely concentrated on plasma confinement using toroidal magnetic fields. Toroidal systems are complex. A simpler magnetic confinement system may provide a valuable platform for understanding fusion plasmas and develop/test the corresponding diagnostics/control systems. The linear mirror machine has delivered good performance with the potential of giving a direct conversion of nuclear energy into electric power. The GAMMA-10 linear mirror confinement system at Tsukuba University demonstrated the principle of the direct conversion of plasma energy into electric power on a small scale from the exhaust plasma in the exterior divertor chamber. In tokamaks the plasma confinement is due to the magnetic field from steady driven toroidal plasma current. The large, exterior end tank-chambers serve as the diverter chambers receiving the wall-plasma interaction away from the hot core plasma. The cylindrical symmetry allows the KAM theorems to guarantee infinite-time particle confinement in the idealized limit no of turbulence and collisions. There is room for creative new solutions in the magnetic confinement of fusion plasmas. We consider the design and properties of a new linear machine with realtime control of biasing end-plate electrons, ECH and NBI heating, high-magnetic mirror fields and the direct conversion of the high-temperature escaping plasma to electric power.
