Funding: The Ministry of Education, Science and Technology of the Korean Government An injector designed for low emittance beam generation as well we high repetition rate and more reliable operation is under development at PAL. By adopting a coaxial high power RF coupler at the gun exit, the gun solenoid can be positioned at an optimum location for low emittance and the cooling water channels can fully surround the gun cavity cylinder for high cooling capacity. With an exchangeable photocathode plug, high quantum efficiency cathode can be used for reducing the drive-laser power requirement and a damaged cathode can be easily replaced with a fresh one. Injector beam dynamics optimization with this gun is presented. |

| MOPD42 | Microbunching Instability Study for the PAL-XFEL Linac | 125 |

Funding: The Ministry of Education, Science and Technology of the Korean Government PAL-XFEL is designed to generate X-ray FEL radiation in a range of 0.1 and 10 nm for users. The machine consists of a 10 GeV linear accelerator and five undulator beamlines. An electron beam is generated at a low emittance S-band photocathode RF gun and accelerated through an S-band normal conducting linac. Microbunching instability may occur when the beam goes through magnetic bunch compressors and beam spreaders. We discuss microbunching instability issues at PAL-XFEL. |

| Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL XFEL) will provide X-ray FEL radiation in a range of 0.1 and 10nm with five undulator beamlines. A undulator section for hard X-ray is designed for 0.1nm SASE FEL. The wakefield effect and its cure by tapering are investigated by tracking simulation. We present FEL simulation study by using GENESIS | ||
