An intense L-band electron linear accelerator is now being commissioned at CESC (Cheorwon Electron-beam Service Center) for industrial applications. It is capable of producing 10 MeV electron beams with 30 kW average beam power. For a high-power capability, we adopted the traveling-wave structure operated with the 2π/3 mode at 1.3 GHz. The structure is powered by a 25 MW pulsed klystron with 60 kW average rf power. The rf pulse length is 7 μs while the beam pulse length is 6 μs due to the filling time in the accelerating structure. The accelerating gradient is 4.2 MV/m at the beam current of 1.45 A which is the fully beam-loaded condition. In this paper, we present details of the accelerator system and commissioning results.
