Removal of cold alpha particles from helical device for fusion

This paper is devoted to the analysis of the new physics mechanism of the removal of cold alpha particles from the fusion helical reactor. Earlier, we have proposed some mechanisms, such as the drift island motion and estafette of drift resonances to remove the test particles, namely the cold alpha particles from the helical device of a LHD type. In that time, we kept in mind the cold alpha particles with the energy W = 350 keV. Now, we concentrate our study on the removal of the helium ash, i.e. cold alpha particles with the energy W = 35 keV while the main plasma ions are confined.
