Abstract: An X-ray source is disclosed comprising a source of high energy electrons that travel along a longitudinal path. Target material lies along the longitudinal path and X-ray radiation is generated due to impact of the high energy electrons with the target. Shielding material is provided around at least a portion of the target. The shielding material defines a slot extending from the target to an exterior surface of the shielding material, to allow passage of generated radiation. The slot has an axis transverse to the longitudinal path. The axis may be perpendicular longitudinal path. The shielding material may define a plurality of slots having transverse axes. The source of high energy electrons may be a linear accelerator, for example. Scanning systems incorporating such sources are also disclosed. The scanning system comprises a conveying system having a longitudinal axis and the radiation source may be positioned so that the longitudinal path forms an acute angle with respect to the longitudinal axis, to decrease the size of the scanning unit as compared to a unit where the longitudinal axis is perpendicular to the longitudinal path. The longitudinal axis may be parallel to the longitudinal path, to form a more compact scanning system. A plurality of slots may be defined in the shielding material and a corresponding number of conveying systems may be provided to examine a plurality of objects concurrently. Methods of generating radiation and methods of examining objects are also disclosed.

Abstract: An x-ray tube target assembly 16 provided. The target assembly 16 includes a target plate element 18 having an impact surface 24, a target rear surface 30, an inner target bore 22, and an outer target circumference 38. The target plate element 18 defines a target plate depth 32 between the impact surface 24 and the target rear surface 30. The target rear surface 30 is formed such that the target plate depth 32 tapers from an increased target plate depth 34 at the inner target bore to a decreased target plate depth 36 at the outer target circumference 38. The target assembly 16 further includes a graphite base element 28 having a base upper surface 42 and a base rear surface 44. The base upper surface 42 is formed to mate with the target rear surface 30.
