Patent ID: 8779398

Claim:
A radiation scanning system to examine contents of objects, the system comprising: first and second radiation sources, each comprising: first and second respective sources of first charged particles; first and second respective accelerators, each coupled to the first and second sources of first and second charged particles, respectively; wherein the first and second accelerators each accelerate the first and second charged particles to first and second energies, respectively; first and second respective targets; a first bend magnet positioned to receive the accelerated first charged particles along a first axis from the first accelerator and to direct the charged particles toward the first target along a second axis different from the first target; and a second bend magnet positioned to receive the second accelerated charged particles from the second accelerator along a third axis and to direct the charged particles toward the second target along a fourth axis different from the third axis; wherein impact of the first and second accelerated charged particles on the first and second targets, respectively, causes generation of first and second radiation beams having first and second energies, respectively: at least one detector positioned to detect radiation after interacting with the object; and a support to support an object to be scanned.
