	For many years Budker Institute of Nuclear Physics produces medium-energy industrial electron beam accelerators. Flexible (due to the possibility of completing with different systems) and reliable accelerators cover the energy range from 0.3 to 3 MeV, and up to 130 mA of beam current, with power up to 100 kW. High electrical efficiency allows the use of accelerators in almost all areas of radiation technology, from cross-linking of the insulation, heat shrinkable tubes and films to the production of foamed polyethylene and modification of rubber blanks for tires. All models have a unified design with a difference in overall dimensions, the length of the accelerating tube, the number of high-voltage rectifier sections, and the type of extraction device. This makes it easy to adapt the accelerators to the requirements of the technology line. ELV accelerator with an energy range of 0.3-0.5 MeV, beam current up to 130 mA, and power up to 100 kW was successfully designed, tested, and installed on the customer’s site. The accelerator is compact in overall dimensions and installed in the local steel shielding. The electron beam is extracted through a two-windows extraction system with one titanium foil 180 mm wide. New accelerators of the ELV type are also being developed. Namely ELV-15 with energy range up to 3.0 MeV and power up to 100 kW. At present time accelerator was assembled and under testing in Novosibirsk.

	For over 30 years, an extraction device has been successfully working in BINP at the ELV-6 accelerator to extract a focused beam of electrons into the atmosphere. The accelerating tube with permanent magnetic lenses was used in this installation. The design of these accelerator tubes with magnetic lenses is rather complicated. Recently, simpler design and high reliability accelerating tubes with big aperture is operating in ELV accelerators. For this reason, the problem number one at present is to develop the extraction device, capable of reliably working with serial accelerator tubes, of the ELV accelerator with power up to100 kW. The lens L1 is located directly at the lower end of the accelerating tube. Passing the lens L1, the beam is focused near the diaphragm D6 and increases to a diameter of 10 mm in the diaphragm D5. For passing the beam along the axis of the diaphragms, there are corrections coils C1 C2 C3. The diameter of diaphragm hole D1 is the most critical, because it determines the flow of gas that should be pumped out in the following steps of the vacuum system. Measurements of the parameters of a high-power electron beam were carried out up to a power of 100 kW. As a result of the made experiments the minimum diameter of the beam at the exit from the extractions device has been 2 mm at the energy of 1,4 MeV and the beam current of 60 mA.

For over 30 years, an extraction device has been successfully working in BINP at the ELV-6 accelerator to extract a focused beam of electrons into the atmosphere.
