Computer Simulation of an Extracted Beam for the Neutron Generator of the Institute for Nuclear Research of the Russian Academy of Sciences

The NG-430 neutron generator at the Institute for Nuclear Research, Russian Academy of Sciences, is being updated. The flux of neutrons produced by the 3H(d,n)4He reaction can be as high as 1013 s−1. Modernization of the neutron generator involves moving it to a new accelerator hall. The generation of several extracted neutron beams is planned. After they pass through the collimator, the neutron fluxes are calculated by the Monte-Carlo method on the basis of the ABBN [4] neutron constants. The parameters of the biological shielding are estimated.
