Abstract: A system for efficient neutron detection is described. The system includes a neutron scintillator formed with a number of protruding parallel ribs each side of the scintillator, forming a first set of ribs and a second set of ribs. The ribs have a protrusion height that provides a selected neutron absorption efficiency. The system includes a set of wavelength shifting fibers positioned between each adjacent pair of ribs on both the first side and the second side. Each set of wavelength shifting fibers are in optical proximity to the adjacent pair of the ribs that set of fibers are positioned between.

Abstract: A neutron detection system includes a neutron scintillator having a thickness greater than an optimal thickness and less than twice the optimal thickness. The system includes a first layer of wavelength shifting fiber optic elements positioned on a first side of the neutron scintillator. Adjacent fibers of the first layer pass light to distinct photo-multiplication devices. The system further includes a second layer of wavelength shifting fiber optic elements positioned on a second side of the neutron scintillator. Adjacent fibers of the second layer pass light to distinct photo-multiplication devices. The two layers may share photo-multiplication devices or use different sets of photo-multiplication devices. The system includes a controller that distinguishes a neutron radiation event from a gamma radiation event in response to electronic signals from the distinct photo-multiplication devices.

Abstract: The present invention relates generally to radiographic imaging of storage devices and more particularly, to a method and device for protecting a storage device from radiographic imaging. Security devices are available which, if their inner workings could be discovered, would be ineffective and therefore would no longer prevent undetected, unauthorized discovery of objects they are designed to secure. An example is a mechanical combination lock which, if the position of its various internal components could be ascertained, would allow unauthorized access. In addition, it is also important in some instances to prevent unwanted radiographic imaging of a storage device so that its contents cannot be ascertained. The current art of radiographic imaging has significantly increased the possibility of this type of intrusion into areas protected by such high security devices. Other types of locks, closures, fasteners, and bolts that protect by mechanically restricting access and which are themselves assumed secured because of the inability of an intruder to ascertain the position of their locking mechanism are also vulnerable to radiographic imaging.
