The results of experimental studies of increasing the net current (sum of the beam current and the plasma current) during propagation of the sequence of 6000 relativistic electron bunches with a charge 0.32 nQ and duration 60 ps for each in a plasma with decreasing density are presented. A plasma with decreasing density in the initially neutral gas (air) is formed by the electron bunches due to the angular divergence of electrons in bunches. The maximum increase of the net current is observed in the pressure range of 10…100 Torr. It was found that during propagation of electron bunches in the open atmosphere also is observed increase of the net current which depends on the distance from the exit of the accelerator.
