| dc.description.abstract | <p> This document reports the results of a study of several parameters of a neutron radiographic system of the direct conversion type, and of their effects on certain image characteristics. These parameters are: thickness of the converter, backing material of the very thin converter layers, level of water in the beam tube, exposure time, and film type. The image characteristics are relative optical density, specific contrast, and unsharpness, the latter interpreted quantitatively through the edge-spread function. Theoretical treatments and empirical data are presented and compared. Emphasis is put on investigations of the perfonnance of thin (~2000 A) layers of gadolinium converter, and on the experimental analysis of the edge-spread function. </p> | en_US |
