Abstract

Characteristics of the calibration quasi-monochromatic secondary electron beam of the S-25R “Pakhra” accelerator of the Lebedev Physical Institute, based on the SP-57 magnet are presented. At the electron beam energy of 280 MeV, a collimator diameter in front of trigger counters of 3 mm, and a copper converter thickness of 1–3 mm, the relative energy resolution and beam intensity are δ = 2.2—4.4% and ~16—23 e^–/s, respectively.
