Abstract:
Preliminary results obtained in the study of single mode optical fiber properties, in order to develop a new radiation dosimeter sensitive to high energy electron beams, are presented in this paper. Optical fiber irradiation was performed at the ALIN-10 accelerator of the National Research and Development Institute for Laser, Plasma and Radiation Physics (INFLPR). This study is based on the physical degradation effect of the optical fiber due to electron beam exposure. This effect can be determined through the measurement of the radiation induced attenuation that is proportional to the exposure dose. Attenuation in the optic fiber was measured before, during and after electron beam exposure for two types of single mode optic fibers and for two wavelength values. The results of the measurements lead to the conclusion that these types of optical fiber can be used for measuring either high or low doses of irradiation.
