Abstract: An analysis is made of the influence of the electron flux on the attenuation of a quartz–quartz optical fiber having a core diameter of 40 μ and a cladding diameter of 130 μ. The initial attenuation of the fiber at the 0.82 μ wavelength was 20 dB.km. Pulsed radiation from an electron beam having a flux density of (4.5–29)×10⁹ electrons·cm^–2·sec^–1 was used. It was established that any change in the electron flux density negligibly influenced the behavior of the induced absorption curve.
