    • 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.
    • 描述了紧凑的双能辐射扫描系统,其包括两个粒子束加速器,每个粒子束加速器被配置为将带电粒子加速到不同的能量,其被定位成平行于待检查对象的运动方向。 相反,加速器可以垂直于输送系统的平面定位。 弯曲磁体系统将每个带电粒子束弯向相应的目标。 可选地,能够将带电粒子加速到至少两种不同能量的单个双能量加速器被定位成平行于物体的运动方向或垂直于传送系统的平面。 提供单个弯曲磁体系统以将每个加速的带电粒子束弯向相同的目标。 粒子束可以通过轨道室弯曲。 两个单独的通道可以通过至少部分的轨道腔室来限定,一个用于具有每个能量的带电粒子。
