Simulation of the high-power electron beam formation and recuperation designed for ion source

This work shows the result of the numerical simulation of the Electron Optic System (EOS), which must be used for the formation and transportation of the high-power electron beam from a long channel. The modeling was taken of the program, which based by using the finite difference non-iniform nets and the model beam from the deformable elements. EOS´ main parameters were following. The electron gun forming of the beams with the perveance is 1,5 A/V^3/2, coefficient of the compress is 200 and the electron beam density is 2,6·10³ A/cm².The magnetic system is create of the special distribution magnetic field of 2000 Gs, which give at addition compression of the beam and transport from the long channel of length 1 meter with minimal pulsations. The collector is use recuperation regime 0,07 U0 for the high economical efficiency.
