Abstract
We obtained a growth of the emitting points and a considerable increase in the emission current in the regime of alternative power supply for initially polished flat metal surfaces. Formed surfaces demonstrate sufficient field emission current stability in vacuum from 10−4 to 10−6 Torr and good tolerance and maintainability of field emission characteristics after series of explosive emission pulses. In an alternative power supply regime, using a grid as one of the electrodes enabled us to output the field emission electron current about 2 mA after accelerating grid.
