The proposal for a new neutron imaging facility at Dalat research reactor

In this paper, we present the results of computation for design of a new neutron imaging facility located at channel No. 3 of the Dalat Reactor. The design has two main parts: The neutron beam collimator and the radiation safety system. For the neutron beam collimator, the computational parameters such as neutron flux, cadmium ratio as well as ratio of neutron dose/gamma dose are reported.
