Mass-spectrometrical study of neutral component of plasma in gas discharge with metal-hydride cathode

Summary form only given, as follows. The composition of the neutral component of a gas discharge in hydrogen, desorbed from the metal-hydride cathode, was studied. On the basis of mass-spectrometrical measurements it was showed that the use of a metal-hydride cathode resulted in the intensification of plasma-chemical reactions with participation of hydrogen in the discharge volume. In this case the anomalous change of the neutral component of the plasma discharge in the range of discharge currents of magnitude 50-200 mA is viewed. The increase of the discharge current above 200 mA leads to disappearance of the discovered anomalies. The chemical composition of the neutral component of the plasma changed only when the metal-hydride cathode was used but no change was observed (the discharge parameters were the same) when the cathode was made of steel and the hydrogen from a cylinder was used.
