    摘要： The present disclosure provides an inspection system and a method of stray field mitigation. The system includes an array of electron beam columns, a first permanent magnet array, and a plurality of shielding plates. The array of electron beam columns each includes an electron source configured to emit electrons toward a stage. The first permanent magnet array is configured to condense the electrons from each electron source into an array of electron beams. The first permanent magnet array is arranged at a first end of the array of electron beam columns. The plurality of shielding plates extend across the array electron beam columns downstream of the first permanent magnet array in a direction of electron emission. The array of electron beams pass through a plurality of apertures in each of the plurality of shielding plates, which reduces stray magnetic field in a radial direction of the array of electron beams.

    摘要： The present specification describes a system for eliminating X-ray crosstalk between a plurality of X-ray scanning systems and passive radiation detectors. The system includes a frequency generator for generating a common operational frequency, a high-energy X-ray source or scanning system coupled with the frequency generator for receiving the common operational frequency and configured to modify the pulse repetition frequency of the high-energy X-ray source or scanning system in order to synchronize with the common operational frequency and a low-energy X-ray scanning system and/or passive radiation detection system coupled with the frequency generator for receiving the common operational frequency and having a processing module configured to remove data associated with the common operational frequency at an instance of time if the high-energy X-ray source or scanning system has emitted X-rays at the instance of time.

    摘要： There is presented a screening system and a corresponding method for screening an item. The screening system includes a detection apparatus (100), a rotatable platform (310) to receive the item, and a mechanical arrangement (320, 330). The detection apparatus has an emitter portion to generate a primary beam of ionising radiation and a detector portion to detect an absorption signal and at least one of a diffraction signal and a scattering signal. The mechanical arrangement is adapted to translate the detection apparatus along a translation axis to scan the item with the primary beam. The screening system may be used for identifying restricted or illicit substances that may be present in some luggage or in mail.
