PAL XFEL project is aiming to produce 0.1 nm coherent X-ray laser to photon beam users. In order to produce such photons, there are 10-GeV electron linac based on S-band normal conducting accelerating structures and a 150-m long out-vacuum undulator system. The project is already started in April 2011, and the 1.1 km-long building is expected to be completed by November 2014. The injector test facility (ITF) which is the first 139-MeV section of the main linac has been installed and is under commissioning in newly added corner of the PLS linac building. In this talk, I will introduce the project in general, performances of ITF, and domestic developments of subsystems such as 200-MW modulator, high power RF components, and precision low power RF systems.
