For the development of an effective cargo-scanning system, an intrapulse energy switching has been tested at the National Centre for Nuclear Research (NCBJ) with the possibility to change the beam energy within a 4 μs pulse of the linear electron accelerator (linac). Modifi cation of the electron energy is achieved through the beam-loading effect in a standing-wave accelerating structure equipped with a triode gun. Construction of the machine and the achieved results are presented in this article.
The new vehicle scanning system Sowa has been developed in the National Centre for Nuclear Research. This innovative device is equipped with a 300 kV X-ray tube, U-shape imaging detector line, transport system, and fully shielded container. Sowa allows for a detailed inspection of the car and the detection of illegal transported items. This article presents the design, applied solutions, and achieved results of Sowa scanning system.
