摘要：

Plasma jet generated by sinusoidal DBD in a tube blown with He is not uniform along its length because of existence of so called "plasma bullets" (ionization waves) travelling in jet each half-cycle. The bullet velocity and the visual shape of plasma jet will change, if to vary the ambient conditions for plasma jet. This work is devoted to the detailed experimental study on influence of the external DC and AC electric field with different amplitude and polarity on the bullet propagation in plasma jet. It has been established that one can change appreciably the plasma bullet velocity and even wholly suppress the bullets in the plasma jet.
