	The presented report contains the description of high-voltage source with output voltage up to 110 kV and output current up to 100 A. The source consist of the chopper with IGBT switches working with a principle of pulse-width modulation and the full H-bridge converter with IGBT switches, both working on programmed from 15 to 25 kHz frequency, and the high voltage transformer powering the four-stage multiplier with the additional capacity filter at output. The transformer and multiplier both is made in oil tank with silicon oil. The additional capacity filter provides low ripple and noise level in working range of output currents. A nominal output voltage of the source is 110 kV. The source can operate in normal mode with series of high-voltage breakdown in output voltage. In the high-voltage breakdown the released in load and matching circuit energy is less than 20 J at maximum operating voltage 120kV. The efficiency of system is more than 80% at the nominally output power 11 kW. The controller of the source is developed with DSP and PLM, which allows optimizing operations of the source. For control of the source serial CAN-interface is used. The description of the source and the test results are presented.

	A linear electron accelerator IDK-6/9МeV has been designed for operation as a source of ionizing radiation in a customs inspection system intended for inspection of large-scale cargos. The main operating mode of the accelerator is the X-ray mode with an energy of 6 MeV, which ensures the penetrability (for steel) more than 300 mm. The operating mode of the accelerator can be quickly changed for 9 Mev, which allows the objects under study to be discriminated based on the organics/non-organics criterion using the "two energies" method. A triode electron source with cathode and grid modulators is applied in the accelerator. A system of collimators located at the output of the accelerating device ensures shaping of an X-ray beam fan-shaped in the vertical plane with an opening angle of 460 directed towards the detector line. The accelerator is equipped with a computerized system of protective interlocks and control, which makes possible its operation both in the setting mode and as a component of the whole customs inspection system.
