  Since January 2008, design study of a free-electron laser has been in progress at Pohang Accelerator Laboratory (PAL) aiming at producing hard X-ray of 0.1 nm wavelength. Electron energy of 10 GeV has been chosen to fit the facility inside the existing PAL site. In-vacuum undulators of 120 meter long (including breaks) with 5.3 mm gap combined with a 800 meter-long conventional S-band rf linac are expected to generate intense x-ray pulses of 5 GW peak power at the saturation length of 100 m. The start-to-end simulation results support initial design parameters based on the theory. Effect of undulator wakefields are examined and 30%reduction in power is anticipated.
