Final report for the tunable driver for the LLNL FEL experiment

This section of the report covers the recent operation of the prototype backward-wave oscillator (BWO) gyrotron. The tube was mounted in its fixture on the superconducting magnet, the beam aligned, and microwaves generated. Initial alignment and operation was performed at low wiggler magnet strength (B{sub w} = 9 G) and thus low {alpha} = {upsilon} {perpendicular}/{upsilon}{parallel}. The microwaves observed under these conditions were at a frequency just above the electron cyclotron frequency … more

High-field, high-density tokamak power reactor

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 relatively small plasma, with a spatially-averaged toroidal beta of only 4%. A unique design for the Nb/sub 3/Sn toroidal-field magnet system reduces t… more
