A neutron imaging facility is located on beam-tube #5 of the 1-MWth PULSTAR reactor at the North Carolina State University. An investigation has been initiated to explore the application of coded imaging techniques at the facility. Coded imaging uses a mosaic of pinholes to encode an aperture, thus generating an encoded image of the object at the detector. To reconstruct the image recorded by the...
Neutron Imaging is a technique for the nondestructive testing (NDT) of materials. It is characterized by its sensitivity to materials composed of low atomic number (Z) elements such as hydrogen. Enhancement of the spatial resolution and the contrast of the obtained images are primary objectives that are continuously being pursued in the development of this technique. An approach of improving the contrast...
A thermal neutron imaging facility has been set up at the North Carolina State University PULSTAR reactor. The PULSTAR is an open pool type light water moderated 1-MWth research reactor with six beam tubes. The present facility is set up on beam tube # 5 of the reactor. The facility is intended to have radiographic and tomographic capabilities. The design of the neutron collimator was performed using...
