Inspection System: X-ray for Cars

 

Inspection systems (IS) are used at customs for cargo scanning when crossing borders. Today new technologies accelerate significantly the operation of border crossings. For example, the new inspection system ST-6035 based on a high power microwave accelerator is capable to inspect cars moving with a speed up to 70 km/h.

Several Ruselectronics plants together with the MSU institute of Nuclear Physics and Scantronic Systems developed the inspection system ST-6035.

The IS is intended for the introscopy (nondestructive testing) of large-size items subjected to customs control such as heavy vehicles and container trucks. With the introduction of the new technology, neither the size or weight of vehicles, nor the increased loading density of different transported goods affect the efficiency of scanning.

The vehicle drives in one gate of the inspection tunnel and leaves through the other one. The tunnel houses rails for movement of a mobile frame, while its components generate X-rays. The frame must be located higher than the item to be controlled, and its height is 4.8 m. The scanning data comes to the computer system where an X-ray image of an item is generated and transferred to the image operator for analysis.

Thus, the IS is similar to the X-ray device for vehicles in terms of its operating principle. The core of the whole system is the linear electron accelerator. Powerful microwave klystrons produced by the Roselektronika holding are used as linear accelerators in ST-6035. For the first time vehicles with a speed up to 70 km/h can be inspected. At the same time the IS design capacity is not less than 20 vehicles per hour.

The IS uses the energy of accelerated electrons not just to produce an image of contents but also to detect the atomic number of the material. Therefore, it is possible to find drugs, explosive or heavy metals within just a few minutes. The high penetrability of ST-6035 eliminates the need to open containers. The system precisely detects materials with a steel penetrability up to 400 mm.
