The system includes a first detector configured to detect incident radiation and output a first detector signal; more than one second detectors surrounding the first detector and configured to detect incident radiation scattered by the first detector, wherein each of the second detectors output a second detector signal, and wherein a signal decay time of the first detector signal differs from the signal decay time of the second detector signals; and a digitizer configured to receive a single input consisting of output signals from each of the first detector and the plurality of second detectors, wherein the digitizer is further configured to simultaneously digitize the signals to produce a digitized output waveform, and wherein a shape of the output waveform is indicative of a presence or an absence of a Compton scatter signal. The systems and methods are also configured to detect pulse pileup, with or without second detectors.

摘要： A dual isotope notch observer for isotope identification, assay and imaging with mono-energetic gamma-ray sources includes a detector arrangement consists of three detectors downstream from the object under observation. The latter detector, which operates as a beam monitor, is an integrating detector that monitors the total beam power arriving at its surface, Ihe f irst detector and the middle detector each include an integrating detector surrounding a foil. The foils of these two detectors are made of the same atomic material, but each foil is a different isotope, e.g., the first foil may comprise U235 and second foil may comprise U238, The integrating detectors surrounding these pieces of foil measure the total power scattered from the foil and can be similar in composition to the final beam monitor. Non-resonant photons will, after calibration, scatter equally from both foils.

摘要： An x-ray screening apparatus having particular use in examining and inspecting luggage and baggage in airport environments is described, the screening apparatus comprising at least one x-ray source, at least one x-ray detector and a sampling volume, e.g. luggage, disposed between the source and the detector. The apparatus is configured such that the at least one detector is able to receive radiation from the at least one source, which radiation has passed through each spatially resolvable volume element within the sampling volume at at least two different angles of incidence, and in which at least two of the source, detector and sampling volume are relatively displaceable so as to enable fully independent relative displacement of each of the source, detector and sampling volume. Interpretation of the detected radiation allows stereoscopic images of the sampling volume to be constructed, providing depth information relating to items within the sampling volume.

摘要： To reduce the size of a photomultiplier (1), a side tube (2) is secured by welding to a stem plate (4) while an inner wall face (2c) of the lower end (2a) of the side tube (2) is maintained to be in contact with an edge face (4b) of the stem plate (4). As a result, there is no projection like a flange at the bottom of the photomultiplier (1). Therefore, though it is difficult to perform resistance welding, the outside dimensions of the photomultiplier (1) can be decreased, and the side tubes (9) can densely abut to one another even if the photomultipliers (2) are arranged when applied. Hence, high-density arrangement of photomultipliers (1) are realized by assembling metallic stem plate (4) and the side tube (2) by, for example, laser welding.
摘要翻译：为了减小光电倍增器（1）的尺寸，侧管（2）通过焊接固定到杆板（4），而侧管（2）的下端（2a）的内壁面（2c）保持与杆板（4）的边缘面（4b）接触。结果，在光电倍增管（1）的底部没有像凸缘那样的凸起。因此，虽然难以进行电阻焊接，但是即使在施加光电倍增管（2）时，也可以减小光电倍增管（1）的外部尺寸，并且侧管（9）可以彼此紧密地邻接。因此，通过例如通过激光焊接组装金属制的阀板（4）和侧管（2）来实现光电倍增管（1）的高密度排列。
