Description

Laval nozzle, which produces supersonic molecular beam, is proven to be an effective fuelling tool for magnetic confinement devices. Details of its design are given in the first part of this paper. Results with supersonic beam injection in HT-7 tokamak show higher efficiency and deeper penetration compared to normal gas puffing. The peaking factor is almost the same with the off-axis pellet injection. Experiments demonstrate that it is a suitable fuelling method of steady-state operation with high density for super-conducting tokamak. (author)
