The 3 MEV, 200 kW high voltage electron accelerator for industrial application

The high-voltage electron accelerator with an energy of 3 MeV and a beam power up to 200 kW comprising a high-voltage generator based on a single-phase transformer-rectifier without iron core is under development. The accelerator is meant for purification of wasted waters, sterilisation of medical products and ecologically safe treatment of logs before transportation with the aim of suppressing the viability of fungus and pests, etc. The main units and systems of the accelerator are described. Versions of the extracting device with output of the beam into the atmosphere or with conversion of its energy into bremsstrahlung are presented. The accelerator is equipped with the unique electron irradiation field shaping system with an elongated turning magnet allowing an irradiation field up to 6 m in width to be produced
