A quasi-monochromatic electron beam of the accelerator “Pakhra” for calibration of detectors

Abstract

Abstract Characteristics of the calibration quasi-monochromatic beam of secondary electrons of the accelerator “Pakhra” of the P N Lebedev Physical Institute of the Russian Academy of Sciences based on the magnet SP-57 are presented. The energy resolution of the beam from a copper converter in the thickness range of 0.1-5 mm and the interpolar gap in the magnet 6 cm amounted to δ = 10−4.5 % in the energy range of the electron beam E = 98−294 MeV, respectively.
