Trapping condition of particles in low-aspect-ratio tokamaks
- 1. Tsinghua Univ., Beijing (China). Dept. of Engineering Physics
Description
The motion of particles in a low-aspect-ratio tokamak was investigated using the drift approximation, with a standard model for the magnetic field and the assumption of the order of aspect ratio. The equations were developed for the motion of a single particle in a low-aspect-ratio tokamak. The criterion for the orbit types in large-aspect-ratio tokamaks was extended. The corresponding criterion in low-aspect-ratio tokamaks was derived and the fraction of trapped particles was found to be higher than in large-aspect-ratio tokamaks
