Dose Equalization in Electron Beam Neutralization of Impurities in Water

A promising design of an irradiator for high-speed electron beam treatment of wastewater in a jet mode is considered. The feasibility of combining technical solutions previously used separately in the design of the ELV-12 and Electron-10 accelerators is demonstrated. A high-speed water jet (>1 m/s) was irradiated from both sides in the gap between two beam windows, directing the beams at an angle of α = 45°−60° to the jet plane. In this case, the useful thicknesses of the jet, which ensured maximum uniformity of irradiation with 1-, 2-, and 3-MeV electrons, as well as the lowest beam energy losses, were 5.2, 13.1, and 20.8 mm at α = 60° and 4.2, 10.7, and 17 mm at α = 45°, respectively. Options for simultaneous irradiation of two and four water jets are being considered.
