The industrial electron accelerators type ILU are developed and produced by the Budker Institute of Nuclear Physics. The ILU accelerators are working in many countries in the industrial lines as well as in some research establishments starting from the beginning of 70-s. These machines are the pulse RF type accelerators with relatively low working frequency – 120 MHz for ILU-6 and ILU-10 and 180 MHz for ILU-8. Their energy range is from 0.8 MeV (ILU-8) to 5 MeV (ILU-10), beam power is up to 50 kW.

The ILU machines are working in various technological processes – radiation modification of polymer tubes and films, polymer pipes for hot water supply, wires, cables, sterilization of single use medical products (syringes, hospital and operation gowns, sets for operations, etc.), decontamination of the medicinal raw.

The ILU accelerators are very compact machines because they do not need the big high pressure vessel filled with insulating gas. The height of the ILU-10 machine (with energy up to 5 MeV) is less than 3 meters. The ILU-8 machine with energy range 0.8-1 MeV can be installed inside the local shield with height of 3.24 m. The local shield can be placed in the ordinary industrial shops.

The ILU accelerators are equipped with several beam extraction devices – linear scanner and scanners with 4 windows permitting to organize the irradiation of the long products (tubes, cables, wires, pipes) from 4 sides. The rewinding devices providing the twist-free transportation of the long products in the irradiation zone are also designed and produced by the Institute.

The new ILU-14 machine for energy range 7.5-10 MeV is under development. This machine is very good for radiation sterilization.
