Method and apparatus for generating sequential beams of penetrating radiation |
摘要 |
An apparatus and method for generating electronically steerable beams of sequential penetrating radiation. Charged particles from a source are formed into a beam and accelerated to a target. Electromagnetic radiation generated by the target is emitted with an angular distribution which is a function of the target thickness and the energy of the particles. A beam of particles is produced by allowing the radiation to exit from an apparatus through a collimator proximal to the target. The direction of the beam is determined by the point of radiation production and the corresponding array of transmission regions of the collimator.
