Abstract
The stability of a beam of negative ions propagating in the parent gas is investigated. It is shown that growth of plasma oscillations with a small growth rate is possible at subcritical currents in a quasineutral regime. The influence of traveling secondary electrons, whose density is small, is also studied. The low-frequency oscillations considered pose the greatest danger to a beam whose velocity is close to the velocity of the secondary electrons.
