Applications of industrial electron accelerators at Samsung Heavy Industries

An industrial electron beam accelerator has been developed at Samsung Heavy Industries with the collaboration of Seoul National University and Russian Budker Institute of Nuclear Physics. The accelerator is a high voltage accelerator using rectifiers and able to deliver 40 mA of 1 MeV electrons in CW mode. Functionally, the accelerator is an electron irradiation processing device and an electron beam scanning system is employed for the uniform irradiation of the electron beam through the extraction window of the size 980 mm/spl times/75 mm. The industrial applications of the electron irradiation processes include combustion flue gas purification process, treatment of industrial waste water containing refractory pollutant, treatment of semiconductor devices, and radio-chemical processes. The major features of the device and its industrial applications will be described.
