The STARFIRE impurity control system is based on a low-Z coated limiter/vacuum system which collects and pumps about 30% of the particle flux at the edge of the plasma. This pumping efficiency, when combined with about a 1.5-T additional margin in the toroidal magnetic field, is sufficient to maintain the steady-state helium concentration to approx. 10% while permitting a tritium burnup fraction at approx. 10%. In order to keep the heat load on the limiter to reasonable limits, about 80% of the alpha-particle energy is radiated to the first wall by injecting a very small amount of appropriate impurity ions.
