Abstract :
An intense L-band electron linac is being installed at CESC (Cheorwon Electron-beam Service Center) for industrial applications. It is capable of producing 10-MeV electron beams with average 30-kW. The beamline consists of an E-gun, a pre-buncher, an accelerating column with a built-in bunching section, focusing solenoids and a beam scanner. The beam dynamics simulation is conducted by the PARMELA code. The nominal capability of the accelerator is obtained by the input RF power into the accelerating column and the input beam current. The optimum operation condition is also obtained by the input RF power into the pre-buncher and the input RF phase difference between the pre-buncher and the accelerating column. As per the simulation on the misalignment effect, focusing solenoids can reduce this effect. In this paper, we present simulation results for the beam commissioning scenario.
