	Pohang accelerator laboratory (PAL) started an x-ray free electron laser project (PAL-XFEL) in 2011. In the PAL-XFEL, an electron beam with 200 pC will be generated from a photocathode RF gun and will be accelerated to 10 GeV by using a linear accelerator. The electron beam will pass through undulator section to produce hard x-ray radiation. In 2015, we will finish the installation and will start a commissioning of the PAL-XFEL. In this paper, we introduce the PAL-XFEL and explain present status of it. Details of the control system will be described including a network system, a timing system, hardware control systems and a machine interlock system.

WEPGF115	LabVIEW EPICS Program for Measuring BINP HLS of PAL-XFEL	966
	H. J. Choi, K.H. Gil, H.-S. Kang, S.H. Kim, K.W. Seo, Y.J. Suh PAL, Pohang, Republic of Korea
	In PAL-XFEL, a 4th generation light source, the HLS (Ultrasonic-type Hydrostatic Levelling System) developed at BINP (Budker Institute of Nuclear Physics) in Russia was installed and operated in all parts of PAL-XFEL in order to maintain observations of the vertical change building floor by the ground sinking and uplifting. For this, a HLS measuring program was written using NI LabVIEW and an EPICS IOC Server was built using the CA Lab which has been developed at BESSY (Berlin Electron Storage Ring Society for Synchrotron Radiation) in Germany. The CA Lab was improved and verified in order to confirm that it could support EPICS BASE libraries V3.14.12, and EPICS CA Client and that the EPICS IOC Server could be easily constructed by CA Lab in a 64-bit LabVIEW. This made Multi-core CPU (Multi-core Processor / Multi-thread Program) resource of 64bit Computer System (64bit Hardware PC / 64bit Windows OS / 64bit LabVIEW Multi-thread Programming) to be 100 percent utilized. This study proposes a configuration process for the HLS measuring program algorithm and a building process for the EPICS IOC Server by using CA Lab.
