Different operating regimes of a source of ions for vacuum neutron tubes developed at the All-Russia Research Institute of Automatics (VNIIA) for portable pulse neutron generators are examined. Experiments demonstrate unstable reproduction of the time dependences of the current in the primary discharge gap of the ion source. The oscillograms of the current and voltage pulses of the arc discharge show the presence of instabilities in the vacuum arc. It is also found that during the first half of the current the burn regime of the arc is strongly nonstationary.
