A Quasi-Monochromatic Calibration Beam of Secondary Electrons at the Pakhra Accelerator

The characteristics of the quasi-monochromatic calibration beam of secondary electrons at the Pakhra accelerator (Lebedev Physical Institute) on the basis of the SP-57 magnet are presented. The energy resolution of the beam with a copper converter 0.1–5.0 mm thick and an interpolar magnet gap of 6 cm is δ = 10.0–4.5% in accordance with the energy in the electron-beam energy range E = 98–294 MeV.
