Abstract

The prototype of Bonner sphere neutron spectrometer of activation type has been created. It is composed of 5-polyethylene spheres with a diameter from 9.0 to 24.5 cm. Indium as activated material inside these spheres is used. We tested the neutron spectrometer, using neutron radiation from converter which was installed at the thirty-MeV output channel of the accelerator complex LINAC-300. As a result of mathematical processing of the measurement data of the induced radioactivity in indium, neutron spectrum was restored. The spectrum, which obtained in this experiment, is similar to the well-known neutron spectrum from the γ, n-reaction with heavy nuclei, which produces neutrons in converter of the accelerator. Energy range of spectrometer was determined and we consider possibility of its expansion. An issue of efficiency, sensitivity and use conditions of the spectrometer is being discussed. The experience, obtained in this work, will be used to optimize the design of a working version of the spectrometer.
