High-field, high-density tokamak power reactor [PDF]

, 1977
A conceptual design of a compact (R/sub 0/ = 6.0 m) high power density (average P/sub f/ = 7.7 MW/m/sup 3/) tokamak demonstration power reactor has been developed. High magnetic field (B/sub t/ = 7.4 T) and moderate elongation (b/a = 1.6) permit operation at the high density (n(0) approximately 5 x 10/sup 14/ cm/sup -3/) needed for ignition in a ...
