Dynamics of Target Plasma Heated by Neutral Beams in a Mirror

Target plasma behavior in a mirror when heated by neutral beams was studied. Considerable changes of target plasma density depending on target quality were found. Neutral beam injection resulted in a considerable decrease of target plasma density for the case of dense subsonic jet being a target. For another case (collisionless target plasma) the neutral beam injection led to increase of target plasma density.

In this paper experimental results, simulations and explanations are given.
