Applying α-channeling techniques to mirror machines can significantly increase their effective reactivity, thus making open configurations more advantageous for practical fusion. A large fraction of α-particle energy can be extracted using rf waves. Effects employed to cool α particles can also in principle be used to heat the fusion ions; the possibility to design a configuration of rf waves that could be used to perform both tasks is demonstrated.

    In this work, two different fluted mixing elements have been investigated by 3D FEM analysis. It has been found that open fluted mixing element has lower temperature losses than closed fluted mixer which can be explained by the presence of the layer, which is slowly rotating very close to the...
