Feasibility Studies of Advanced Bootstrap Driven Tokamaks

Tokamak reactors burning advanced fuels must operate at high plasma densities and temperatures. Under these conditions large bootstrap currents can be generated with modest externally driven seed currents. Large total currents give rise to long energy confinement times and a safe ignition margin. The paper discusses high pressure DT–, DD– and D³He–tokamak reactor concepts based on the bootstrap drive of the toroidal current.
