Linear Electron Accelerator LUE-75 of Yerevan Physics Institute at Energies of 10−75 MeV

The results to increase the rated energy of the linear accelerator of electrons LUE-75 from 50 to 75 MeV are presented. The characteristics of the beam are investigated, and the measured energy spectra of the obtained beams are presented in the range of 50–75 MeV at the average intensity up to 10 μA. The modernization of the elements of magnetic optics for the parallel transfer path was performed, and the beam was tracked to the end of the transport channel.
