The test of operation of this antenna demonstrated that it can effectively produce plasma of different composition: pure hydrogen, helium-oxygen mixture, hydrogen-nitrogen mixture. Simultaneously with this program, two calorimetric probes were specially developed and constructed in the Laboratory of Prof. Miran Mozetsch for the use of them in the vacuum chamber of the Uragan-2M stellarator, when the second stage of the Contract will be provided in 2014 year on the optimization of RF conditioning of the vacuum chamber walls of the Uragan-2M fusion device.
