In the present work there has been investigated nature of redundant one-electron noise of image converter by counting characteris­tics method, that provides high accuracy and reliability of obtained results. It has been experimentally proven that the cause of redun­dant one-electron noise of converter is autoelectronic emission. Proceeding from the obtained results there have been offered ways to reduce autoelectronic emission up to its disapperearance: replacement of evaporator shape, training in argon atmosphere before the manufacture of photocathode and impulse high-voltage training after the manufacture of photocathode.
