Frequency regime of high current relativista electron beams interacting witn various gaseous media

Constantly growing application of high current relativistic electron beams (REB) to produce non-equilibrium plasma in plasma-chemical reactors, to pump lasers, etc, necessitates the investigation of REB interaction with various gaseous media and mixtures. To solve the problem of a plasma chemical reactor based on REBs it is necessary to account for the effects of the intrinsic electromagnetic fields of plasma-beam system upon plasma chemical processes^/1/. Here we pay a particular attention to the possibility to increase the pulse repetition rate. It is expected that by multipulse treatment of gaseous media the efficiency of the subsequent pulses could be increased due to lowering the rate of development of large-scale instabilities.
