Abstract
Pacific Northwest National Laboratory (PNNL) has developed and patented a process for fabricating cerium-activated, lithium-silicate, scintillating fibers via a hot-downdraw process. The fibers respond to gamma rays and thermal neutrons and the signals from each can be differentiated. This technology is presently being commercialized by Oxford Instruments, Nuclear Measurements Group. Several flatpanel devices and deployment applications have been evaluated for safeguards applications such as SNM monitoring and human-intrusion detection. Examples of such detectors and their design and performance parameters are discussed.
