description: Thesis is dedicated to the preparation front-end electronics for PAX experiment, using particle beam of COSY in Forschungszentrum JÃ¼lich. A mock-up of neutron attenuator has been designed at the Ioffe Institute and JSC "Technoexan" in the framework of ITER diagnostic system development. The attenuator is intended for suppression of radiation background caused by neutron flux in a gamma-ray spectrometer. The attenuator is a steel cylindrical casing of 400 mm in length, filled with pellets of pressed lithium hydride powder with natural ratio of lithium isotopes. The housing is hermetically welded at both ends. The work presents the results of studies of characteristics of mock-up version LiH neutron attenuator manufactured at the Novosibirsk Chemical Concentrates Plant. Measured attenuation factor for neutron radiation from 241Am-Be source for the energy range above 5 MeV was 90.8, which is in good agreement with Monte Carlo simulation data. Results of the work will be used at the development of gamma-ray spectrometer in the neutral particle analyzer system of the ITER tokamak. The main consumer of the diagnostic system development project is "Project center ITER" (Institution of the State Corporation for Atomic Energy âROSATOMâ).
