Electron Accelerators for Novel Cargo Inspection Methods

Several new methods of cargo inspection with MD were recently introduced to address the above-mentioned limitations: dual-energy methods based on Scintillation-Cherenkov detectors [1]; multi-energy method based on intrapulse time-varying of spectral content of x-ray [1], [2]; multi-energy method utilized ramping-up energy packet of short x-ray pulses [3], [4]; and methods based on multi-energy betatron [5], [6]. All of these methods have electron accelerators as a core element. However, the accelerator requirements and, thus, their designs, are different for each system. In this paper, we will discuss the requirements for the accelerators, provide some details about their designs, and present several novel solutions for current and future projects.
