  Pohang Accelerator Laboratory(PAL) is developing a SASE X-ray Free Electron Laser based on 10 GeV linear accelerator. Bunch compressor (BC) systems are developed to be used for the linear accelerator tunnel. It consists of three(BC1, BC2, BC3H) hard X-ray line and one(BC3S) soft X-ray line. BC systems are composed of four dipole magnets, three quadrupole magnet, BPM and collimator. The support system is based on an asymmetric four-dipole magnet chicane in which asymmetry and variable R56. can be optimized. This flexibility is achieved by allowing the middle two dipole magnets to move transversely. In this paper, we describe the design of the stages used for precise movement of the bunch compressor magnets and associated diagnostics components.

PAL-XFEL facility is an 1110 meters long laboratory for generating X-ray free electron laser. The radiation ranges between 0.1 and 10 nm. The facility consisted of three halls, a 780 m S-band linac hall for 10 GeV, a 225 m undulator hall for hard X-ray and a 105 m hard X-ray beam-line hall for user experiments. A soft X-ray undulator and a soft X-ray beam-line hall which have the length of 110 and 100 meters respectively are built in the facility. The building construction was completed in February 17, 2015. The installation of devices had been started accordingly.
