Concept of a Facility of Neutron Radiography and Tomography at the Research Reactor WWR-K in Almaty, Kazakhstan

Abstract

At the research reactor WWR-K (Institute of Nuclear Physics, Ministry of Energy, Almaty, Kazakhstan) work on the creation of a new experimental facility for research using neutron radiography and tomography method has begun. It is planned that the facility will form a neutron beam with a cross section of 200 × 200 mm, with a characteristic parameter L/D of 130, using a vacuum collimator system. To obtain neutron radiographic images, a specially designed detector system based on a ⁶LiF/ZnS scintillation screen and a high-resolution high-sensitivity video camera with a rotated mirror will be used. To protect the video camera from radiation, a two-mirror optical system is proposed. The paper presents a schematic diagram and description of the main components of the experimental setup.
