N2 - The electrophysical parameters [current–voltage (I–V) characteristics and breakdown voltages] of an abnormal direct current discharge in helium, hydrogen, and in its’ mixtures are investigated under conditions of minimizing the presence and influence of uncontrolled impurities in the operating medium, cathode material, and structural elements of the discharge cell. The results demonstrate that the presence of molecular hydrogen in the operating gas, even with minimal amounts, including implanted in the near-surface layer of the cathode of the discharge cell, leads to changes in the electrophysical parameters of the gas discharge. It is associated with the dependence of the cathode emission properties on the emitting layer modification by implantation of the operating gas particles into its surface and increasing the effective multiplication coefficient in the cathode layer due to the excitation and ionization of helium by fast heavy impurity particles.
