Abstract: The present invention is a directed to a non-pixelated scintillator array for a CT detector as well as an apparatus and method of manufacturing same. The scintillator array is comprised of a number of ceramic fibers or single crystal fibers that are aligned in parallel with respect to one another. As a result, the pack has very high dose efficiency. Furthermore, each fiber is designed to direct light out to a photodiode with very low scattering loss. The fiber size (cross-sectional diameter) may be controlled such that smaller fibers may be fabricated for higher resolution applications. Moreover, because the fiber size can be controlled to be consistent throughout the scintillator array and the fibers are aligned in parallel with one another, the scintillator array, as a whole, also is uniform. Therefore, precise alignment with the photodiode array or the collimator assembly is not necessary.

Abstract: A method for measuring a dose of irradiation with a beam of ionizing radiation capable of creating Cherenkov radiation, in which a scintillator for emitting scintillation light, whose intensity is a function of the dose of this beam irradiating this scintillator, is arranged below this beam, the scintillator is coupled, via an optical fiber, to a device for measuring the light emitted by the scintillator, and the quantity of light transmitted by the optical fiber is measured, is described. The light emerging from the opposite end of the optical fiber is filtered using two bandpass filters having cutoff bands in different parts of the spectrum, the intensity of the light coming from these two filters is measured a plurality of times, and the pluralities of quantities of scintillation light and Cherenkov radiation are calculated on the basis of these measurements to deduce a first irradiation dose value.

Abstract: The invention provides an improved neutron detector of fast neutrons and may be used particularly in the advanced detection technologies for the non-intrusive interrogation of passengers luggage, large cargo and trucks. The proposed detector of fast neutrons consists of fiber block (parallelepiped), which is assembled of the layers of polymer scintillating fibers, oriented in two mutually perpendicular directions and optoelectronic system of registration of optical irradiation. Optoelectronic system of registration is based upon position sensitive photo-receivers, which are optically coupled with corresponding of fiber edges. Optoelectronic system consists of two local optical sub-systems. The first (main) sub-system matches each individual fiber edge with corresponding element of two-dimensional position sensitive photo-receiver. The second (complementary) sub-system matches columns and rows of fiber edges with corresponding individual pixels of fast linear photo-receivers.

Abstract: A portable dosimetry system measures individual seed strengths of fully loaded multi-seed holders. The system includes a 5 mm diameter scintillating fiber disposed in a groove on a rigid bed. A photomultiplier tube (PMT) is supported on the rigid bed and is coupled to an end surface of the scintillating fiber. Attachments are provided for positioning multi-seed holders adjacent the peripheral surface of the scintillating fiber, and movable shield plates are provided for inhibiting stray radiation (produced by neighboring seeds) from reaching the scintillating fiber. The system is useful for calibrating 100% of the seeds in a holder in less time than it currently takes to calibrate 10% of the seeds in the holder.
