摘要：

Experiments involving plasma improvement, confinement scaling, bootstrap currents, and edge fluctuations have been carried out in the Advanced Toroidal Facility (ATF) torsatron [Fusion Technol. 10, 179 (1986)]. Average densities n̄e≤9x1019m-3 have been obtained, with global energy confinement times τE*≤20 msec. Confinement times generally follow the stellarator/torsatron empirical scaling law, τSL = 0.17XP-0.58ne 0.69B0.84a2R0.75 (with τSL in seconds, power P in megawatts, density ne in 1020 m-3, and plasma radius a and major radius R in meters). Gas injection during neutral beam injection (NBI) causes increases in ne, so that τE* does not decrease during NBI. Edge plasma fluctuations are found to exhibit a mode change near the peak of the energy confinement time. Plasma currents observed during electron cyclotron heating have been identified as bootstrap currents. © 1990 American Institute of Physics.
