High-power Accelerator for Environmental Applications

A high-power electron accelerator has been developed for environmental applications by EB TECH Co. Ltd. and BINP. This accelerator, which has double extraction windows, can deliver an electron beam with a power up to 400 kW at 1 MeV through 3 irradiators. Titanium foils are used as the window material and are cooled both by water and a blowing air jet. High voltages are generated through the inductions of the coils in the main accelerator body and SF(6) gases are used to protect against electrical discharges. The first such accelerator was installed in 2005 at the Daegu Dyeing Industrial Complex, Korea, for treating industrial wastewater from textile dyeing industries.
