| Popis: | A scheme of the system for pumping active gas media by electron beams injected into a gas volume located in a multipole magnetic field is proposed and engineering solutions are presented, which were used in the development and making of this system. The possibility of changing a resistance to a plasma current initiated by a relativistic electron beam is promising for the additional control of the kinetics of processes in the active gas medium with the aim of increasing the energy input efficiency. The scheme proposed in the paper allows the combination of the pumping of the gas medium by an electron beam with pumping by a controllable discharge initiated by this beam in electric fields of the beam. The energy input of electron beams to the gas medium located in a quadrupole magnetic field is analysed by the Monte-Carlo method. The calculations demonstrate a high efficiency (90%) of the beam energy transfer to the gas and the possibility to control the energy-input profile. |
