Non-destructive analysis of materials by neutron imaging at the TITAN facility

Abstract

Since 2019, the TITAN neutron radiography and tomography facility have been operating at the WWR-K research reactor. The experimental station is intended for a wide range of applications in various fields of science. Since the launch, several interesting works have been carried out to study the internal features of lithium-ion batteries and geophysical materials. The spatial resolution of the detector system was sufficient to visualize the internal elements of the lithium battery and to separate individual grains of the pyrite mineral in the rock sample. This paper presents the technical parameters of the experimental setup and the results of the recent applied research.

Investigation of Neutron-Physical Characteristics of the Irradiation Capsule Designed for Radiation Coloring of Topaz in the WWR-K Reactor

“…Проведены радиографические/томографические исследования внутренней структуры экрана и изучено распределение порошка карбида бора в алюминиевой матрице. При нейтронной радиографии исследуемый объект облучается коллимированным потоком нейтронов, где различие в нейтронных сечениях поглощения для разных элементов объекта дает информацию о внутреннем распределении неоднородностей исследуемых материалов [8].…”

Neutron-tomographic study of the structural features of a bronze mirror found in the Akterek burial complex

“…The collimation of the thermal neutron beam is formed by an aperture system which consists of several pinholes of different diameters. Depending on the needs of the experiment, it is possible to vary the diameter of the aperture system for different modes: high resolution or high intensity [14].…”
