Study on selective injection of a compact toroid and a supersonic gas jet, and its fueling process

We conducted an experiment to inject an accelerated compact torus(CT) plasma into a cell filled with neutral gas by using a CT injector which is a kind of magnetized coaxial plasma gun, and then attempted to promote neutralization of the CT through charge-exchange reaction to produce a high speed gas jet. As a result, a high-speed gas jet comparable to the accelerated CT has been successfully produced, although plasma partially remained. This leads to selective injection of a CT plasma and a super-sonic gas jet.
