Doublet III neutral beam injection system overview and status report
The Doublet III tokamak currently in operation at General Atomic is designed to operate initially with a toroidal magnetic field of 2.6 T, 5 V-sec of ohmic heating flux swing, a plasma current of 2 MA, and a plasma temperature of 1 keV. Early in 1980 it is planned to add the two 80 keV hydrogen neutral beam injectors now in fabrication to the machine to produce approximately 3 keV temperatures utilizing approximately 7 MW of auxiliary beam heating. Ultimately, an approximately 20 MW, six injector system will be constructed and employed to produce >5 keV reactor-grade plasmas which will simulate breakeven conditions. An overview of the system and facility design is presented with a particular emphasis on the cryogenic system and test facility. A brief discussion of the schedule and the status of construction and fabrication is also presented.
