    摘要： A method of dewatering a hydrocarbon storage tank carrying a first fluid layer that includes a first hydrogen concentration and a second fluid layer that includes a second hydrogen concentration includes receiving, from a sensor and by a processor communicatively coupled to the sensor, a value representing an amount of backscattered neutrons sensed by the sensor. The sensor is attached to a surface of a wall of the tank adjacent a fluid outlet of the storage tank. The sensor is configured to sense neutrons backscattered from the first fluid layer and an interface layer. The method includes comparing, by the processor, the value to a threshold, and actuating, by the processor, a valve fluidically coupled to the outlet of the storage tank to drain the first fluid layer from the storage tank while preventing the interface layer from leaving the storage tank.

    摘要： An internal imaging system has a radiation source and a plurality of detectors positioned to receive portions of the plurality of collimated beams that have been attenuated by interaction with the target. The radiation source is configured to irradiate a target with a plurality of collimated beams of radiation. Two of the plurality of collimated beams of radiation may have different beam shapes. Another internal imaging system includes a radiation source configured to irradiate a target with at least one collimated beam of radiation and at least one detector. A planar rotating collimator is positioned adjacent to the radiation source and is configured to form the at least one collimated beam. The at least one detector is positioned to receive attenuated portions of the at least one collimated beam. The radiation source may be or include a neutron source. The detectors may be or include a plurality of neutron converters.

    摘要： A borehole logging tool is lowered into a borehole traversing a subsurface formation and a neutron detector measures the die-away of nuclear radiation in the formation. Intensity signals are produced representing the die-away of nuclear radiation as the logging tool traverses the borehole A signal processor, employing at least one neural network, processes the intensity signals and produces a standoff-corrected epithermal neutron lifetime signal to correct for standoff from the borehole wall encountered by the detector as the logging tool traverses the borehole. The signal processor further generates a porosity signal from the standoff-corrected epithermal neutron lifetime signal derived from measurements in borehole models at known porosities and conditions of detector standoff. A log is generated of such porosity signal versus depth as the logging tool traverses the borehole.

    摘要： Neutron elastic scatter resonance is employed for the noninvasive interrogation of objects as for example to detect explosives and narcotics in closed containers. A resonant scattering spectrum of the object is obtained by projecting a collimated, monoenergetic beam of neutrons onto the object, varying the energy of the beam and measuring the scattered neutrons as a function of the beam energy. The thus generated spectra and analyzed so as to determine either the pressence of particular elements of interest or the relative ratios of those elements. Ratios so determined may be compared with corresponding ratios established for contraband items. If the ratios fall within the range for contraband, an alarm indication is provided. The present invention provides method and apparatus for contraband detection.

    摘要： A RADIOACTIVE SOURCE OF ENERGY EMITING NEUTRONS IS PLACED ADJACENT A SUNKEN HULL AND NEUTRONS PASS RELATIVELY UNIMPEDED THROUGH THE STEEL HULL AND, IF INCLUDED, AN INTERNAL THERMAL INSULATOR TO A COMPARTMENT INTERIOR. IF THE COMPARTMENT IS UNFLOODED, MOST NEUTRONS CONTINUE ON THEIR WAY, BUT IF THE INTERIOR IS FILLED WITH WATER, A GREAT MANY OF THE NEUTRONS ARE PARTIALLY BACKSCATTERED AS THEY ENCOUNTER THE WATER MEDIUM WITH A PERCENTAGE OF THE BACKSCATTERED NEUTRONS IMPINGING ON A PARTICLE DETECTOR. THE PARTICLE DETECTOR PRODUCES SIGNALS REPRESENTATIVE OF THE BACKSCATTER INTENSITY TO AN INDICATOR WHICH PROVIDES AN INDICATION TO A DIVER AS TO WHETHER OR NOT A COMPARTMENT IS FLOODED. BY RELOCATING THE INVENTION ALONG THE VERTICAL DIMENSION OF THE COMPARTMENT AND NOTING WHERE THERE IS AN INSIGNIFICANT LEVEL OF BACK-SCATTERING, THE LEVEL TO WHICH THE CHAMBER IS FLOODED IS DETERMINED FROM THE VESSEL''S EXTERIOR.
