Abstract: The invention concerns radiographic equipment. The equipment includes a source of substantially mono-energetic fast neutrons produced via the deuterium-tritium or deuterium-deuterium fusion reactions, comprising a sealed-tube or similar generator for producing the neutrons. The equipment further includes a source of X-rays or gamma-rays of sufficient energy to substantially penetrate an object to be imaged and a collimating block surrounding the neutron and gamma-ray sources, apart from the provision of one or more slots emitting substantially fan-shaped radiation beams. Further included is a detector array comprising a multiplicity of individual scintillator pixels to receive radiation energy from the sources and convert the received energy into light pulses, the detector array aligned with the fan-shaped beams emitted from the source collimator and collimated to substantially prevent radiation other than that directly transmitted from the sources reaching the array. Conversion means are included for converting the light pulses produced in the scintillators into electrical signals. Conveying means are included for conveying an object between the sources and the detector array. Computing means are included for determining from the electrical signals the attenuation of the neutrons and the X-ray or gamma-ray beams and to generate output representing the mass distribution and composition of the object interposed between the source and detector array. The equipment further includes a display means for displaying images based on the mass distribution and the composition of the object being scanned.

Abstract: The specification describes an instrument and a method for determining information about an object (J), only one side of which is available for examination. The method involves exposing the object to gamma-rays and measuring the position and/or time of arrival of gamma-rays at a detector (D). The instrument includes a source of gamma-rays (S) located so that at least some gamma-rays impact upon the object, and a detector surrounded by a shield (C) having an aperture (A) for facing at the object to be studied. The detector is capable of measuring the position and/or time of arrival at the detector of gamma-rays passing through the aperture.

Abstract: Se describe un analizador de difraccion de rayos X por dispersion de energia en linea (EDXRD) para el analisis mineralogico de material en una corriente de proceso o una muestra. El analizador incluye una fuente de rayos X colimada para producir un haz divergente de rayos X policromaticos y un detector de rayos X de resolucion de energia, y un miembro sustancialmente transparente a los rayos X que tiene la forma de un solido de revolucion que es circularmente simetrico sobre un eje central entre la fuente de rayos X colimada y el detector de rayos X de resolucion de energia, una superficie exterior del miembro transparente a los rayos X que se puede colocar junto al material que se va a analizar. Un colimador de haz primario esta dispuesto adyacente a o dentro del miembro sustancialmente transparente a los rayos X para prevenir sustancialmente la transmision directa de rayos X policromaticos emitidos desde la fuente al detector. El analizador esta configurado de manera que el haz divergente de rayos X policromaticos se dirija hacia el elemento sustancialmente transparente a los rayos X, y donde el detector de rayos X de resolucion de energia recoge una porcion del haz de rayos X difractado por el material y emite una senal que contiene informacion de energia de los rayos X recogidos y difractados.
