Abstract :
The high power electron accelerator (FANTRON-I) for industrial applications is under development at Physico-technology laboratory, KAPRA (Korea Accelerator and Plasma Research Association). To validate the acceleration scheme, single pass acceleration experimental setup using nonagon shape coaxial cavity has been installed. The experimental setup consists of an electron gun, coaxial cavity, bending magnet, beam diagnostic and dump chamber, RF amplifier, vacuum and cooling system. A Rogowiski type gun with Th-W wire filament was used as an electron gun and produced 20 kV, 0.8 mA electron beam. A 159.41 MHz, 3 kW RF system consists of an oscillator, 100 W solid state amplifier and 3 kW tetrode amplifier. The bending magnet composed of main and supplementary magnet for weak focusing was designed, fabricated and tested. In this paper, the test results of the acceleration system components using nonagon shape coaxial cavity are analyzed and the design status of FANTRON-I are presented
