Abstract
Compact, dual energy radiation scanning systems are described comprising two particle beam accelerators, each configured to accelerate charged particles to different energies, positioned parallel to a direction of movement of an object to be inspected. The accelerator may be positioned perpendicular to a plane of the conveying system, instead. Bend magnet systems bend each charged particle beam toward a respective target. Alternatively, a single dual energy accelerator capable of accelerating charged particles to at least two different energies is positioned parallel to the direction of movement of the object, or perpendicular to a plane of the conveying system. A single bend magnet system is provided to bend each accelerated charged particle beam toward the same target. The particle beams may be bent through an orbit chamber. Two separate passages may be defined through at least part of the orbit chamber, one for charged particles having each energy.
