Electron-optic system of the multicharge ion source (MIS-1)

Results obtained in designing of the electron-optic system (EOS) of the multicharge ion source (MIS-1) are reported. This system forms an extended (∼2 m) electron beam of power 1 MW. The length of the MIS-1 ion trap with an electron beam density greater than 2*103 A/cm2 is increased to 1.5 m. Recuperation of the electron beam energy is envisaged in the collector.
