	The activity for beam intensity increasing and beam use efficiency improvement is under progress in INR linac. An important stage is the development and implementation of the Beam Pulse Separation System in the accelerator intermediate extraction area (160 MeV). The system is intended for distribution the beam pulses between Isotope Production Facility (up to 160 MeV) and the Experimental Facility located downstream of the accelerator exit. The report describes the upgrade of intermediate extraction area as well as the first results of experiments with the beam.

	A bending magnet with a power supply system has been designed and manufactured in the NIIEFA for the Institute for Nuclear Research RAS to ensure simultaneous operation of the linear accelerator in the experimental and isotopic systems. The arrangement has been installed and adjusted in the INR RAS. In the paper are described a schematic and principle of operation of the arrangement ensuring the bending of a part of the beam macroimpulses to the isotopic system with a frequency of up to 50 Hz. The adjustment 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.

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.
