Capabilities of RFNC-VNIITF in conducting of experiments on testing of the units for tritium system of fusion neutrons source based on gasdynamics trap are shown.

Basic scheme of test-bench for mastering of the principal elements of vacuum technological complex of gasdynamics trap with using deuterium- tritium mixtures is shown also. One of the basic test-bench elements, which is proposed to be mastered on the first stage, is system of utilization and purification of working gas mixture, which will be pumped from gasdynamics trap. Designer decisions of the model of this test-bench unit are sketched, and edition of the proposed experiment is described.
