High Voltage ELV Accelerators for Industrial Application (family of accelerators and tendency of development) | |
|
||
| The ELV electron accelerators are DC machines purposed for wide application in various technological processes. ELV accelerators are the most popular Russian accelerators not only in Russia but in China and South Korea also. The new set of ELV accelerators with power of electron beam up to 100 kWt inside energy region 0.8 -2.5 MeV was developed. These accelerators were adapted for existing technological processing and for requirements of operation on industrial plant. The main design of accelerators is the same but electrical and electronics circuits were modified. In our Institute was developed the set of underbeam devices that increase the possible application and improve the quality of electron beam treatment. | ||

| Due to the necessity of pilot scale test facility for continuous treatment of wastewater and gases on the spot, a mobile electron beam irradiation system mounted on a trailer has developed in EB TECH Co. Ltd. and Budker Institute of Nuclear Physics. This mobile electron beam irradiation system is designed for the individual field application with self-shielded structure of steel plate and lead block which will satisfy the required safety figures of ICRP. Design parameters are limited by the allowable total weight and height of the trailer on the road which controlled by National Authorities. Therefore, the output parameter of electron beam is designed for 0.7 MeV and 20 kW through 600 mm window. Shielding of a mobile electron accelerator has been examined by Monte Carlo technique (MCNP code). Calculations using two different versions (version 4c2 and version 5) of MCNP showed agreements within statistical uncertainties, and the highest leakage is far below the tolerable radiation dose limit. This mobile unit will be used for on-site test of liquid waste and gaseous waste in Saudi Arabia by Saudi ARAMCO and U.S.A. by PELE Technology Inc. together with EB TECH Co. Ltd. This unit could treat up to 500m3 of liquid waste per day or 10,000 Nm3 of gases per day. | ||

| WEPPC056 | Improving of Uniformity of the Electron-Beam Treatment of Materials by ELV Accelerators | 557 |
|
||
| The problem of the absorbed dose distribution during the EB treatment by ELV accelerator is considered. The value of the absorbed dose is determined by the speed of scanning electron beam along the accelerator exit window (i.e. the movement across the conveyor). It is determined both by the shape of scanning current and by the geometry of scanning magnets. A simple way to improve the dose distribution near the edges of the extraction device of accelerator is suggested. It allows to provide the non-uniformity less 4%. | ||
