A result of numerical simulation of acceleration of the test electron bunch following a sequence of relativistic electron bunches in the rectangular dielectric resonator when filling the drift channel with plasma of different density is provided. We have found out that at change of plasma density the linear growth of energy gain of test bunch electrons is observed. It is connected with structure ordering of longitudinal accelerating electric field in the resonator and also with increase in its amplitude. It is due to that at periodic injection of drive bunches on resonator axis the areas with the increased plasma electrons density are formed.
