This study presents spatio-temporal development of the ionisation waves (IWs) along one dielectric tube with an extra alternating electric field. A pulsed direct current power supply is used for generating the IWs, and another alternating current power supply is used for altering the distribution of electric fields along the dielectric tube. The measurements show that the propagation velocity and density of IWs are strongly affected by the external electric field. The direct relation between external electric field and the velocity of the IWs is demonstrated. Further analysis indicates that the external electric field can be utilised to control the propagation of the IWs, resulting in a change of their density and velocity.
