Abstract: An X-ray based inspection systems providing radiographic imaging for cargo inspection and material discrimination with adaptive control dependent upon characteristics of the cargo under inspection. A packet of X-ray pulses with controllable packet duration is produced that allows multi-energy material discrimination in a single scan line and real-time adjustment of packet duration to adapt to cargo attenuation. In addition, adaptive dynamic adjustment of the operational characteristic of the detector channels increases the effective dynamic range and as a result increases the penetration and range of thicknesses where material discrimination is possible. The material discrimination technique is applied within a single packet of short pulses of several hundred nanoseconds. Feedback from the detection system is used to control the packet duration of each packet of X-ray pulses in order to adapt scan parameters to the object that is being imaged.

Abstract: A system for use in oil drilling applications includes a scintillator material having a cubic garnet host and praseodymium distributed within the host. The scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation. A radiation detector optically coupled to the scintillator detects the emitted ultraviolet radiation. In a method for detecting oil, a radiation detector is optically coupled to a scintillator material having a cubic garnet host and praseodymium distributed within the host, wherein the praseodymium acts as an activator, and wherein the scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation. The detector and the scintillator material are lowered below the surface of the earth, and ultraviolet radiation emitted by the scintillator material in response to stimulating gamma ray radiation reflected by hydrogen bearing compounds indicating the presence of oil is detected by the detector.

Abstract: An imaging optical arrangement serves to image an object illuminated by X-rays. An imaging optics serves to image a transfer field in a field plane into a detection field in a detection plane. A layer of scintillator material is arranged at the transfer field. A stop is arranged in a pupil plane of the imaging optics. The imaging optics has an optical axis.

Abstract: A method and corresponding apparatus are provided for measuring neutron spin precession in an electric field with high sensitivity suitable for practical applications in non-destructive testing, imaging, and the like. Production of a neutron beam with a polarization vector P is followed by transmitting the spin-polarized neutron beam through a sample region in which there is a target generating an electric field, polarization-analyzing the transmitted neutron beam with an analyzing direction orthogonal to P, detecting an intensity of the polarization-analyzed neutron beam; and mapping the detected neutron-beam intensity to a field-strength value for the target electric field.
