Název v původním jazyce

Commissioning tests of the new neutron radiography facility at the LVR-15 reactor

Popis výsledku v původním jazyce

Neutron radiography represent a non-destructive testing imaging method, similar to X-ray radiography. Its application starts in cases where X-ray radiography may hit its limits. In recent years a neutron radiography facility has been built at one of the spare horizontal channel of the LVR-15 research reactor in Rez, Czech Republic. The present facility is a result of a pilot project of reintroduction of neutron radiography after 20 years at the LVR-15 reactor. The horizontal channel HK-1 was modified for this purpose, which was equipped by a neutron filter and an irradiation box. A Timepix based detector was developed for the facility and installed coupled with a sample positioning device. These can be fully remotely controlled via a computer and online measurements can be carried out and processed immediately. Before the facility was put into its full operation in 2016 several test measurements were done prior, to test the limitations of the facility. The test measurements were focused on neutron imaging of test samples for various scientific fields like material science, structure engineering, geology, palaeontology, cultural heritage preservation, etc. The realized measurements have shown the limits of the facility caused mainly due to the level of beam collimation. This aspect require measurements where the sample is in near- contact geometry with the detector to achieve a reasonable image resolution. But despite this feature the new facility still provides unique non-destructive testing capabilities supplementary to Xray radiography.
