Electron beam with an energy 1 MeV in the recuperation regime

The power achieved value for industrial accelerator is about a hundred kilowatts. Typically an energy of such machines is in the range of 0.5 - 2.5 MeV, and current 100 mA. Further development is limited by the possibilities both of the accelerating system and beam extraction device. Simultaneously the charged heavy particles beams development and their application has shown to be promising in using electron cooling in energy region a few GeV/nucleon. An electron beam with an energy ≅ 1 MeV and current 1 + 10A is needed for this purpose. Therefore the device at energy of 1 MeV and 1 A continuous electron beam recuperation was built for studying the power accelerating system and testing possibility of forming electron beam for high-voltage cooling. In this paper, the authors propose specific problems of the electron cooling device as: high vacuum, long size of electron tract, low transverse velocities of electrons, longitudinal magnetic field high uniformity could be solved. The main problem for such a device is to achieve a continuous high-power electron beam, its transportation in the relatively low 1 kG) magnetic field, the placed in to magnetic field accelerating tube behavior, a possibility of 1 MeV beam recuperation. Such an approach enabled simplifying and speeding up the device development. Besides that the design was performed in such a way, that the main elements of the device could be used in future machines: device for beam extraction
