摘要
The scaling of the transport rate of particles with normalized gyroradius has been measured for L mode discharges in the DIII-D tokamak. Both the helium diffusivity and the effective electron particle diffusivity were measured. In these L mode discharges, the particle diffusivities tend to scale like the ion thermal diffusivity, which scales between Bohm-like and Goldston-like. Non-zero inward pinch velocities are measured. Like the diffusivities, the pinch velocities increase with gyroradius.
