Abstract
Production of neutral beams consisting of the mixed hydrogen isotopes is of interest for the purposes of diagnostics, since it enables us to study the relaxation process of fast ions trapped in plasma using the neutron diagnostics. In addition, the injection of mixed deuterium–tritium beams for heating and sustaining the plasma could greatly simplify the expensive systems for isotope separation in fusion reactors. In this work, the Doppler spectroscopy technique is used to experimentally determine the fractional content of ions with different masses in the ion source beam consisting of the mixed hydrogen isotopes (hydrogen–deuterium beam). The experience acquired in this field is proposed to be further used to optimize the conditions for plasma generation in the ion source in order to obtain an ion beam with the mixed isotope composition and specific characteristics required for various applications.
