摘要： A fissile neutron detection system includes a neutron moderator and a neutron detector disposed proximate such that a majority of the surface area of the neutron moderator is disposed proximate the neutron detector. Fissile neutrons impinge upon and enter the neutron moderator where the energy level of the fissile neutron is reduced to that of a thermal neutron. The thermal neutron may exit the moderator in any direction. Maximizing the surface area of the neutron moderator that is proximate the neutron detector beneficially improves the reliability and accuracy of the fissile neutron detection system by increasing the percentage of thermal neutrons that exit the neutron moderator and enter the neutron detector.

摘要： An object radiography apparatus includes a radiation source configured to generate and emit an electromagnetic radiation for radiographing an object, a detector device, which is arranged in such a way that the emitted electromagnetic radiation which passes at least partly through the object impinges at least proportionally on the detector device, and which is configured to generate a radiograph of the object. In addition to the detector device, a sensor arrangement is provided, which is configured to determine a radiation characteristic variable assigned to the radiation source. An evaluation unit is configured to determine or to receive a quality parameter of the detected radiograph, to evaluate the radiation characteristic variable and to make a statement about a state of the detector device and/or of the radiation source on the basis of the quality parameter and the radiation characteristic variable.

摘要： The invention provides a charged particle sensor (10) for detecting and measuring ionic current generated by charged particles resulting from ionization processes, comprising: a housing (16), a detection electrode (14) enclosed within the housing for collecting the charged particles, and an electrometer (12) having an input connected to the detection electrode for receiving a DC input signal therefrom and an output (18) for supplying a DC measurement signal as output. The housing comprises an electrostatic screen (16) for screening the detection electrode from external electric fields, whereby to reduce the sensitivity of the detection electrode to such fields. The electrostatic screen includes an electrically conducting screening sheet (26) provided as a second electrode facing the detection electrode and formed with interstices to allow the entry of radiation into the housing, and the second electrode and the detection electrode are arranged to be maintained in use at a bias voltage with respect to one another so as to effect charge separation amongst charged particles resulting from ionization processes and thereby produce an ionic current impinging on the detection electrode.

摘要： Disclosed are systems, devices and methodologies relating to an ion induced impact ionization detector and uses thereof. In certain implementations, the detector can include a dielectric layer having one or more wells. An anode layer defining apertures to accommodate the openings of the wells can be disposed on one side of the dielectric layer, and a cathode such as a solid resistive cathode can be disposed on the other side so as to provide an electric field in each of the wells. Various design parameters such as well dimensions and operating parameters such as pressure and high voltage are disclosed. In certain implementations, such an ion detector can be coupled to a low pressure gas volume to detect ionization products such as positive ions. Such a system can be configured to provide single ion counting capability. Various example applications where the ion detector can be implemented are also disclosed.
