SCITEK Consultants Ltd, in conjunction with RadSci Consultancy Ltd, have designed and manufactured a complete Cold Neutron Radiography facility for installation on one of the beamlines of a nuclear reactor at a Chinese research centre.
The Cold Neutron Radiography system uses neutrons to build up three-dimensional pictures of the interiors of static objects or of operating machinery , highlighting the presence within them of the hydrogen present in water, oil, fuel or corrosion products. This imaging technique is similar to X-Rays and can be used to identify internal corrosion in aircraft components, to study internal capillary passageways in plants and to identify the make up or the presence of damage due, for example, to corrosion in bronze components of archaeological objects.
The equipment includes:- the main neutron shutter, an automated neutron aperture selector, an 11m long vacuum flight tube, neutron beam profiler, 3-axis object handling system (up to 300 kg objects), turntable for neutron tomography (up to 25kg objects) and a neutron imaging system based on an Andor iKon-L 4 Mpixel cooled CCD camera and neutron-sensitive scintillation screen.
Scitek and RadSci have also designed the neutron beam stop for the Chinese customer to manufacture. All components of the system are controlled from one of three PCs by the customised software (based on LabVIEW). Also included in the system are the programs Octopus for CT reconstruction and VGStudio Max for 3D image display and analysis.
