Currently, the field emission properties of polyacrylonitrile carbon fibers are actively studied. Field emission properties of polyacrylonitrile carbon fibers with a febrile structure, a diameter of 7 microns and a heat treatment temperature of 1500-2600 oC are considered. The value of the maximum emission current removed from a single carbon fiber increases with increasing heat treatment temperature. Changes in the current-voltage characteristics during the operation of the field emission cathode and under the influence of adsorption of residual gas molecules are analyzed. A way to reduce the emission current fluctuations is shown.
