Abstract: The results of an analysis of the mechanisms of losses of a high-energy atomic beam in the connecting duct of the TUMAN-3M tokamak are presented. A numerical model is developed describing the effect of reduction of the duct transmission coefficient and allows reducing the power losses of the beam injection. Based on the model, a new duct with an increased cross section was constructed and installed on the tokamak. It was found that the replacement of the duct with the new one led to a 1.5– to 2-fold increase in the integral rate of the neutrons originated from dd-reactions of energetic deuterons with the target plasma.
Keywords: high-temperature plasma, tokamak, Neutral Beam Injection, high-energy particles, fusion neutron production.
