The strong influence of hydrogen recycling on the IONOTRON-046 plasma injector operation was found. The transitions were even observed from deposition by pulsed erosion (DPE) regime of the IONOTRON operation, which characterized by strong electrode erosion into pulse implantation doping (PID) regime with low electrode erosion. Physical mechanisms of such behavior are considered using the results of measurements of an outgassing rate from the titanium electrode rods used in IONOTRON-046 by means of mass spectrometry and thermal desorption methods, measurements of current- and voltage-waveforms, and spectroscopic studies of plasma emission. A possible practical use of the observed effects is also discussed.
