Compact electron linac LU-7-2 for radiography of large-scale objects

At RFNC-VNIIEF there was started up a compact LU-7-2 linear electron accelerator designed for industrial application in the field of radiography of objects with a large mass thickness as well as for development of radiation technologies. For accelerator microwave power supply there was used a magnetron operating on a wavelength of 10.7 cm with a pulse power of 2.5 MW. Accelerating structure was created on the basis of a circular disc-loaded waveguide with varying geometry of accelerating cells, operating on a traveling wave of 2π/3 mode. Electrons are injected by a diode type 50 kV electron gun. The achieved parameters allow to use the accelerator for radiography of objects with a large mass thickness

Development of radiation technologies on VNIIEF LU-10-20 linac

In the present article there is given a review of a number of last works conducted at VNIIEF with the use of this accelerator

Production of radiation destructant from spent butyl rubbers on the linac LU-10-20

Radiation methods of materials modification applied in technological chains can have significant economical and ecological advantages as compared to the established chemical, thermal and mechanical methods. Each year the problems of nature resources economy through the use of production and consumption wastes acquire a more significant value, as it allows to solve also ecological issues along with economical ones. This is mostly acute in relation to polymeric systems based on saturated rubbers, for example butyl rubber (BR) used in tyres industry, as due to their high resistance to the action of oxygen, ozone, solar radiation and bacteria they contaminate the environment for rather a long period. At VNIIEF and KSPU there were carried out experiments on application of electron beams with energy from 6 to 10 MeV for radiation destruction of spent rubber based on butyl rubber. Reclaim is tested in the formulation of initial diaphragm mixture, rubber mixture for producing rubberized fabric, roofing
